Tip 1: Why the water becomes cloudy in the aquarium


In the article, I will give some tips on eliminating the multitude of contaminating particles that have appeared in the aquarium water. I'll tell you what reasons could have caused this problem, why the water became turbid. Enumerate the actions that help to avoid turbidity in the aquarium.

What to do if the water starts to grow cloudy - a quick way to remove dregs

Negative changes in the system are most often signaled by the turbidity of the water, which deteriorates the appearance and creates a danger to pets. To successfully combat it, you need to understand the reason and find an effective way to eliminate it.
It is recommended to observe the turbidity following the filling of a new aquarium or the replacement of a large amount of water in the old 5-7 days (maximum 2 weeks). Transparency should be back.

Why clean the soil and decor of soluble, bulk materials? From them a lot of dirt at the bottom of the aquarium. Wooden decorations are pulled out and soaked in running water for a week, then they can be returned back.

Soil pollutes water

The extra inhabitants are transplanted to another place: resettlement will benefit everyone.
If possible, you should replace the filter with a more powerful one, or carefully clean and wash the existing one, change the filler, add a filter layer. To absorb harmful substances put activated carbon for a couple of weeks.
The overgrown green algae are well eaten by daphnia and snails, are removed with the help of a willow branch laid in water. They also die if you cover the aquarium from sunlight for several days.
If the consequences of overfeeding, lack of attention to the underwater world (food remains, waste) are found, you need to:

  1. Arrange fish fasting for 2-3 days,
  2. To clean the inside of the aquarium, remove dirt from the walls and bottom,
  3. Replace more water than usual with fresh water - up to 1/3 of the total volume.

In extreme cases, you can use chemicals to correct a difficult situation. Although many amateurs find it wrong to interfere so much with natural processes, this method often helps.

How to deal with and get rid of the mute. Produced by German manufacturers Tetra and Sera, Cidex. Among them are drugs that quickly neutralize the products of decay, accelerate the growth of beneficial bacteria, connecting small particles of turbidity.

Sera Cidex

Finally, if all the products have been tried, it remains to transplant the pets to another place, rinse the aquarium with contents, replace the water completely and start running from scratch.

Causes of water blooming in the aquarium, how to remedy the situation

Why is the aquarium water transparency broken? There are several explanations.
In the process of preparing a new aquarium and the first settlement of tenants, the water in it often becomes cloudy. The main reasons are:
Lack or insufficiency of preliminary washing of an aquarium, soil, decor. Light grains remaining on them pollute the water.
Natural imbalance with changing environmental conditions. After adding fresh water, active reproduction of beneficial and harmful microorganisms begins, which forms a white turbidity until the onset of biological equilibrium.
Installation of scenery from unstable materials. Such objects gradually begin to rot, crumble, dissolve, polluting the environment.

Dirty elements of the aquarium also spoil the water

The appearance of a turbid liquid in a long-populated aquarium indicates, mainly, the owner’s violation of pet care rules. It may be:

  1. Filter clogging, insufficient power, or simply no. Debris remains in the water.
  2. Rare, poor-quality cleaning of the aquarium. Because of the dead parts of the plants that were not cleaned in time, the dead inhabitants, the waste of life, the rotting and multiplication of bacteria begins, the water becomes cloudy and yellow.
  3. Feeding over measure. Not eaten feed particles sink to the bottom and float on the surface, quickly rotting.
  4. Excessive number of residents. When overpopulation produces much more organic waste, not every filter will cope with such a load.

Why does the water begin to turn green, bloom, stink

However, they can also cause the water to cloud.
Distribution of unicellular algae is most likely when installing an aquarium in direct sunlight. Some of these plants are in the water. The abundance of bright light in combination with uncleared food debris, the lack of a filter causes their rapid growth, called flowering, with an unpleasant odor.
The lack of lighting will lead to the death of large plants, so it also does not need to be allowed, otherwise the aquarium will begin to stink and eliminate stagnant water and stains on the glass is difficult. If you do not wash the aquarium, then the murk will not go anywhere.

Prevention of turbidity, greening - elimination of turbidity by replacing and cleaning the filter

If the water begins to turn green-bloom, thus making it difficult to view the underwater world, it is reduced if you follow the recommendations on the preparation of the aquarium, accommodation, care.
Together with a mini-pond, you should purchase high-quality equipment (filter, aerator, heater, lighting lamp) and run it slowly. To install, select a flat surface, without hitting the direct rays of the sun. The soil is thoroughly washed before laying, wooden objects are soaked. There is no better method than a good filter.

Backlight and filter are very important.

What to do next, water is poured carefully, without eroding the bottom coating (you can on a framed plate). Plants are planted not earlier than in a week, the light for them is turned on for half a day after another 3 days.
It is not necessary to change the turbid water during the first 3 weeks, the new portion will also turn white. When the turbidity disappears, then in a week you can gradually populate future residents, in groups of 1/3 with an interval of 2 weeks. Surely need snails, bottom fish and other cleaners.

Feeding is arranged daily 1 times in small portions, preferably with live food. For 10-15 minutes, the food should be eaten, after which the leftovers are removed each time.
In the current mode, it is required to rinse the filter in time, collect waste from the soil weekly and replace 1/5 of the volume with fresh water separated by 2-3 days.

The risk of contamination of the domestic water body, pet poisoning is minimized while observing the rules of care. And there are many methods to remove the dregs from the houses of your fish. You must always follow two rules. First, monitor the cleanliness and keep the water from blooming and the second is a good filter. The customized biosystem preserves itself, and it will please the eye for a long time, calm the nerves.

Aquarium is a beauty

From what the water in the aquarium muddy

An aquarium is a microworld where organisms appear and die. It consists of a fine interconnection of fish, plants and bacteria.

When you create a new aquarium in a few days there is a huge number of bacteria, excessively breeding in water. This leads to its turbidity. This process is quite normal and natural. Before you run the fish in an aquarium with new water, you just need to wait a few days until it clears itself. Due to lack of food, most bacteria will become extinct, and the biological balance of water will normalize. Changing water in this case is strictly forbidden, because it will also become cloudy. It is best to add some water from the old aquarium, where the balance has long been established. If this is not available, nothing terrible, the balance in the water itself is settled, it just takes more time for this.

Another cause of muddy water may be overfeeding fish. Excess feed, which your pets do not have time to eat, sink to the bottom and begin to rot. As a result, the water begins to deteriorate. In such an environment, the inhabitants of the aquarium can not feel good, and their long stay in bad water will destroy.

When a large number of fish in the aquarium and, at the same time, poor filtration of water, there is its turbidity. The inhabitants of such an environment will certainly begin to poison the body with decay products, which will lead to their death.

The cause of muddy water can be algae. There is a certain type, which, due to excessive reproduction, leads to clouding of the environment in the aquarium and at the same time emits an unpleasant smell. Another problem may be excessive lighting or accumulation of excess organic matter at the bottom, which stimulates the rapid growth of microscopic algae, and as a result water will bloom. It becomes opaque with a greenish tinge. With a lack of light, the plants in the aquarium will turn brown and begin to rot, which will ruin the habitat of the fish and harm their health.

What to do with muddy water in the aquarium

To deal with muddy water is not difficult, the main thing is to understand the causes of turbidity and follow certain rules in the future.

First you need to determine the cause of the turbidity of the water. If it is in overpopulation of the aquarium, then you should strengthen the filtering or move some fish to another place. If the reason is the accumulation of excess food at the bottom, then you need to reduce the dose of food or purchase bottom fish that will eat up the settled food. If there is a problem with lighting, you need to darken the aquarium or enhance the light. To prevent the rapid growth of algae, it is recommended to start fish or snails that eat plants. In order to maintain biological balance in the aquarium, it is imperative to have a good filter that matches the size of the water tank. You need to understand that in the aquarium the water is alive, and to maintain balance you need to maintain certain conditions. It does not recommend the use of chemicals, they can lead to even greater environmental disturbance and will require a longer recovery.

In maintaining balance in water, its change plays an important role. After launching a new aquarium, it is not necessary to change the water for 2-3 months until the balance is improved. In the future, the water should be replaced 1-2 times a month. At the same time merging only 1/5 of the total volume of the aquarium and adding as many new ones. If you change more than half, then the habitat is disturbed, which will lead to the death of the fish. In small aquariums, water can be replaced less frequently, provided there is a good filter.

The water in the aquarium quickly becomes cloudy: the reasons

A lot of aquarium fish lovers notice that when they buy a new aquarium and fill it with water, it will quickly become cloudy. Why it happens? Reason for this phenomenon rapid reproduction of microorganisms. Getting into the new environment, there is a rapid growth of colonies of bacteria, which causes a change in the transparency of the water in the aquarium.

As a rule, it passes quickly. A week later, the water will again become transparent, biological balance will come. That is why, after filling the new aquarium with fresh water, it is not recommended to immediately release the fish. It is better to wait until the peak of the reproduction of microorganisms passes, and the environment will again become transparent.

The best option when purchasing an aquarium is to pour water from the old one there. In this case, there will already be a formed microclimate, and the water will not become turbid. It is also not recommended to change the water, it will lead to imbalance.

But even in the old aquarium, where its microclimate and fauna has already formed, the environment may cease to be transparent. As a rule, this leads to Two main reasons:

  • excessive feed. If you pour more food into the aquarium than fish can eat, it will sink to the bottom. As a result, the environment will become turbid due to debris and due to the rapidly proliferating bacteria,
  • bad filtering. When there are few fish in the tank, and there is enough space for everyone, poor filtering has little effect. Another thing when the territory is densely populated. In this case, due to poor water treatment, decay products will remain in it (from food debris or from waste products of the inhabitants of the aquarium). As a result, the water will quickly become muddy and the fish, and other people can quickly die.

Sometimes the transparency of the aquarium can be spoiled by the growth of algae, while from there it starts to smell bad. In this case, it is said that the liquid "bloomed". There are several reasons for this:

  • excessive lighting. Algae begin to multiply rapidly,
  • lack of lighting. If there is little light, the algae will die off and begin to rot,
  • a large amount of organic residue at the bottom. It also leads to the growth of microscopic algae.

If the environment in the aquarium began to grow cloudy or "bloomed", then this must be urgently addressed. Otherwise, you can destroy all its inhabitants.

The fight against "muddy" water

If the environment in the aquarium has become turbid, then the cause of this phenomenon is eliminated first. When overcrowded enhanced filtering system. If this is not possible, then it is necessary to move some of the inhabitants to another place.

When feeding, make sure that all food is eaten. If its remains are noticed on the bottom, then the amount of food should be reduced. There is another option to cope with such a problem - it is hooked into the aquarium bottom fish. They will eat the remnants of food accumulated at the bottom and will not allow the water to become muddy.

When "blooming" of the aquarium (rapid reproduction of algae) is necessary reduce illumination. For example, remove it to a darker corner of the room or set a screen. If the algae began to rot from a lack of light, then additional lighting should be provided.

With excessive algae growth can be fought in another way. Knock into the aquarium world of fish that feed on vegetation or run snails. They quickly cope with thickets.

In general, following the right biological balance in an aquarium is the most important thing. The health of all inhabitants will depend on the cleanliness of the habitat and the proper balance of microflora in it.

Special additives are available for sale, adding which (according to manufacturers) balance is quickly restored. But most aquarists do not use them. Yet such drugs, although safe, are still chemistry. It is better to properly set up a cleaning and lighting system, and also to avoid overcrowding in an aquarium. And then the liquid will not smell unpleasant and quickly grow turbid.

Do I need to do a replacement?

Having dealt with the question of why the aquarium water is cloudy, you can talk about replacing it. Some will think: is it necessary to change it at all? It turns out replacement is needed, but only do it carefully.

If the aquarium is just running, then it is not worth changing the water in it for 2-3 months. During this time, it will form its own microclimate. Then you can gradually change the water. This is done every 15-30 days (depending on the effectiveness of the filtering system). At the same time, the volume of new water should not exceed one fifth of the capacity of the aquarium. Even such a replacement will lead to a small imbalance, which will completely disappear only on the second day.

If you change the water more often or do it in large volumes, you can damage an established biological system. As a result, the inhabitants of your underwater world may die.

Experts even recommend making replacements less frequently than every month, of course, subject to the normal operation of filters and cleaning systems. In this case, the fish will feel good and the water will not become muddy and will not smell bad.

clouding of an established aquarium

If the clouding of a young aquarium is forgivable to an aquarist, then dregs in the old pond are his sin! Violation of the biobalance in well-established water bodies is often due to oversight, due to the lack of basic care, due to ignorance or unwillingness to know what is happening in the aquarium. The exculpatory causes of the clouding of the old aquarium are “whiteness after the treatment of fish,” that is, when aquarium chemistry and preparations were used in the aquarium. Like any "medicine" aquarium chemistry has side effects, in particular the violation of biological equilibrium.
What happens in the old aquarium? Why does the water grow cloudy in it?
And almost the same thing happens as in a young aquarium. But, if I may say so, in regressive order.
To make it even clearer to you, let's break the aquarium biological chain into links. NITROGEN CYCLE is as follows.
(remnants of dead organics, fish food, feces, etc.)
decompose under the action of bacteria in

(the strongest poison, destructive for all living things)
under the action of another group of bacteria is decomposed into

(less dangerous, but also poisons)
further decompose to

and out of the aquarium water
As you understand, this process is multistage and has its own nuances.
For those that want to study it in more detail, I recommend to go to the forum thread NITRITES AND NITRATES IN THE AQUARIUM. And now imagine what will happen in the old aquarium, if one of the links, for one reason or another, falls out? That's right - dregs! Sorry for the tautology))) Unlike the dregs in a young aquarium, the turbidity in the old aquarium not only spoils the appearance of the aquarium, but is also very dangerous. Происходит следующее, под действием не выводящихся ядов, иммунитет рыбок ослабевает, их защитные механизмы ослабевают и становятся неспособными сопротивляться «вредным» - болезнетворным бактериям и грибкам (которые всегда находятся в воде). В итоге рыба заболевает и если не провести вовремя лечение – рыба умирает. Таким образом, можно сделать вывод о том, что нарушение биологического баланса является первопричиной гибели аквариумных рыбок.In fairness, it should be said that the saturation of aquarium water with excess ammonia, nitrite and nitrate - can occur without turbidity of aquarium water. What is even worse, because the enemy is invisible.


or how to set up biobalance
First of all, you need to make regular cleaning in the aquarium, do not overfeed the fish. Remember that only the constant and correct replacement of aquarium water for fresh water is an effective way to get rid of poisons.
ATTENTION: Substitute water in a young aquarium, in order to get rid of turbidity is not necessary. In the first month, the water in a young aquarium should generally be changed less frequently and in smaller volumes. Water should "infuse."
Drugs that eliminate the biological clouding of the aquarium - preparations setting biobalance:
Almost all aquarium brands in their arsenal have a line of products that customize the biological balance.
The essence of these drugs can be divided into those that:
- neutralize poisons (nitrites and nitrates),
- promote the growth of colonies of beneficial denitrifying bacteria or are a ready concentrate of these bacteria.
To achieve the maximum effect, you should use these drugs in a complex. Especially with a flash of nitrite and nitrate.
Preparations that neutralize nitrites and nitrates Zeolite is an ion exchanger, in fact, as well as aquarium coal is an absorbent. But, unlike coal, which is not able to “tighten” nitrites and nitrates, zeolite copes with it perfectly. Zeolite is used not only in aquarism, it is widely used in other areas of human life. Therefore, it can even be bought by weight.
Zeolites are a large group of similar in composition and properties of minerals, aqueous aluminosilicates of calcium and sodium from the subclass of frame silicates, with glass or pearlescent gloss, known for their ability to give and reabsorb water, depending on temperature and humidity. Another important property of zeolites is the ability to ion exchange - they are able to selectively release and reabsorb various substances, as well as exchange cations.
Aquarium preparations containing zeolite.

Fluval zeo-carb - a filler for filters zeolite + absorbent carbon.
This is a combination of Fluval activated carbon and Fluval Ammonia Remover. Working together, these highly effective means of active filtration, which eliminate pollution, odors and color, and at the same time, remove toxic ammonia:
- Protects an aquarium from toxic ammonia.
- At the same time, coal adsorbs waste materials, dyes and drugs from water.
- Reduces the phosphate content in water.
The combination of the two products frees up space in your filter for other types of filtering.
Aquael ZeoMAX Plus - zeolite in the form of small crumb, removes ammonia and phosphates, stabilizes pH.
Due to its chemical structure, it provides excellent absorption of organic pollutants, nitrogenous compounds and phosphates that are toxic to fish, which are a consequence of the metabolism of aquarium inhabitants.
Zeolite should not be left in the filter for more than one month.

For more information about the advantages and disadvantages of zeolite, see the forum thread "Nitrites and nitrates", namely HERE.
The drug acting at the chemical level.

Sera toxivec - a drug that at the chemical level instantly eliminates NO2NO3. Since this is chemistry, it is recommended to use it as a preventive measure and once.
Immediately removes hazardous contaminants, life-threatening fish and filter bacteria, from aquarium water. Equal effectiveness against different types of pollutants makes this tool especially valuable.
Sera Toxivec instantly eliminates ammonia / ammonia and nitrites. Because of this, it prevents their transition into nitrates and helps prevent the growth of irritating algae.
In addition, Sera Тoxivec eliminates aggressive chlorine from tap water. It is also effective as an eliminator of disinfectant residues and applied drugs.
At the same time, he is capable of even more: binds toxic heavy metals such as copper, zinc, lead, and even mercury. Therefore, these pollutants cannot harm fish and beneficial bacteria in the biofilter. Due to this, the frequency of water changes can be reduced.
If necessary, for example, at particularly high levels of contamination, an increase in the applied dose of the agent is allowed. Repeated depositing is allowed in one to two hours.
Drugs that promote the growth of beneficial colonies
bacteria or are ready concentrate bacteria
Tetra Bactozym - This conditioner, accelerating the process of stabilization of biological equilibrium, in the filter and aquarium. Suitable for fresh and sea water.
Tetra Bactozym accelerates the conversion of nitrites to nitrates and contains a concentrate of enzymes and substances that contribute to the development of beneficial aquarium microflora. It makes water crystal clear and provides enzymatic decomposition of dissolved organics. The use of an air conditioner reduces the damage done to the beneficial microflora when changing water and washing the filters, and restores microorganisms weakened or damaged by the use of medications.
We draw your attention to the fact that biostarters contain various types of cultures of bacteria and enzymes. Too high or low temperatures reduce their effectiveness.
Tetra NitranMinus Perls (granules) - for reliable reduction of nitrate content in water. The drug eliminates the nutritional element necessary for the development of algae, which allows for a long time to improve the quality of water, thereby reducing the need for care for the aquarium.
- lowering the level of nitrates by 12 months by biological means.
- the growth of algae is significantly restrained.
- just buried in the ground.

Tetra NitrateMinus (liquid conditioner) - biological reduction of nitrates, calculated for 12 months. Improves water quality. Interferes with formation and growth of seaweed (duckweed). Designed for all types of marine and freshwater aquariums.
Convenient dosing: 2.5 ml of a new liquid NitrateMinus for every 10 liters of water, once a week.
Like NitrateMinus in granules (Pearls), liquid NitrateMinus facilitates the processing of nitrates into nitrogen and lowers carbonate hardness. A decrease in nitrates by 60 mg / l leads to an increase in carbonate hardness of approximately 3 KH. With regular use of the drug after replacing water, the pH of the water stabilizes and the risk of falling acidity decreases.
Full compatibility, NitrateMinus is based on biological processes in an aquarium and is completely safe for fish. It combines perfectly with TetraAqua EasyBalance and other Tetra products.
Sera bio nitrivec (Sera bio nitrivek) - a drug for quick launch of the aquarium. Special blend of various high-quality cleansing bacteria for aquariums. Sera nitrivek prevents the accumulation of ammonium and nitrite. The use of Sera nitrivek allows you to put the fish in the newly created aquarium after 24 hours after application. When entering the water bacteria
begin to act immediately. The resulting effect is stored in
for a long time, giving a crystal water to the aquarium water.
There are other drugs of identical orientation. I recommend sharing Tetra Bactozym and Tetra NitranMinus Perls.
And for NO2NO3 flashes use zeolite.

How else can you achieve a “good biobalance”?

- Biological equilibrium is more stable if there are live aquarium plants in the aquarium. Plants partially absorb the decay elements of living organics and thereby reduce their concentration. The more aquarium plants, the better. I recommend to read the article. AQUARIUM PLANTS ALL FOR BEGINNERS.
- Aquarium snails and fish “orderlies” will help you in cleaning the aquarium. The “detachment” of the same coil snails copes with dying leaves and organic matter perfectly. Fish nurses also help in this matter. The majority of aquarium catfish can be attributed to them: corridors, antsistrusy, girinoheiliusy, aquatic sequences, thoracacums, and many others.
- It is advisable to use multistage filtration of aquarium water. And also use other methods that improve water quality, for example, phyto filtration.

Tip 1: Why the water becomes cloudy in the aquarium

Muddy water in an aquarium is a common problem that even experienced aquarists sometimes encounter. It can be fatal for your fish. To avoid this, you need to understand the causes of this trouble and eliminate them.

The question "opened a pet store. Business is not going. What to do? "- 2 answers

Tip 2: Why the water becomes cloudy

A properly equipped and properly maintained aquarium in which biological balance is maintained may not require changing water for a long time. The problem of water turbidity often occurs in novice aquarists, who believe that caring for fish is only in abundant and timely feeding.


1. Water becomes turbid due to small particles of soil that have been washed out of it, washed away during careless filling of the aquarium with water. After they settle to the bottom, the water will again become clear. Do not replace water completely when it is not required. Using a rubber or glass tube, periodically remove the dirt that accumulates on the bottom and add the required amount of fresh water, making sure that its temperature coincides with the water in the aquarium.

2. Water may also become turbid in a new, newly equipped aquarium, due to the reproduction of single-celled organisms. This phenomenon is called "infusorial turbidity". Do not rush to settle an aquarium prepared and filled with water, wait a few days. Another harmless cause of turbidity - loosening of the soil by fish digging in it - is easily eliminated by placing a layer of thoroughly washed sand on the bottom.

3. The turbidity of the water can be caused by the appearance of a large number of putrefactive bacteria that are very harmful to fish and plants due to too high a concentration of fish in the aquarium or improper feeding. Follow one of the basic rules of aquarism: "It is better to underfeed than overfeed."

4. If you forget to clean up the remnants of food and rotting plants in time, this can also provoke a rapid reproduction of bacteria. In addition, turbidity can be caused by poor filtration and blowing of water, as a result of which accumulation of metabolic products occurs in the aquarium, which serve as an ideal medium for mass reproduction and feeding of bacteria. To avoid such consequences, squander excess fish and improve the filtration system.

Refuse dry feeds or give them a little and watch them to be eaten as soon as possible. Place in the aquarium snails, which are willing to clean up edible remains.

Water in an aquarium quickly becomes turbid: what reasons can?

Turbid water in the aquarium is not uncommon when starting a home pond. This is due to the fact that a bacterial outbreak occurs, which is caused by the active reproduction of single-celled organisms in water. That is why the settlement of fish is better to postpone for a while. You need to wait some time to establish a balance in the water, and it will become transparent. If you change the water, then again there will be turbidity of water in the aquarium.

If the water in the new aquarium dims, it should take at least 5-7 days. Only after that you can safely run the fish. During this time biological balance will be restored. To speed up this process, you can add some water from the old aquarium.

Often, the aquarium becomes turbid due to overfeeding the fish. Water spoils quite quickly if food is not completely eaten by the inhabitants of the mini-reservoir. It settles at the bottom of the tank and can spoil the life-giving moisture. This is another common cause of this problem.

Video - muddy water in the aquarium

Water turbidity in the aquarium can be expected as a result of poor filtration of water. The cleaning system must be well thought out. This is especially important when there are many inhabitants in an aquarium. If the problem is not resolved in time, it can cause the fish to become poisoned with decay products. "Residents of the reservoir" of this relationship may not survive.

The problem of green and muddy water in an aquarium can be hidden in a microscopic alga, or rather, in its rapid growth. If organic matter accumulates at the bottom or too much light is directed at the reservoir, then microscopic algae can actively grow. But when the lighting is not enough, the algae will turn brown and begin to rot. If the water in the aquarium quickly becomes cloudy and smells unpleasant, the root of the problem may lie in the growth of blue-green algae.

Aquarium dimmed: what to do?

If such trouble still happened, you need to determine why the water in the aquarium dimmed. Only the exact answer to this question will set the course for further action. If the root of the problem is hidden in the overpopulation of the aquarium, you need to reduce the number of its inhabitants or to increase filtration. If at the bottom the remnants of the uneaten food are deposited, the number of servings needs to be reduced or settled by the bottom fish, which will eat up the remains.

If you can figure out why the water in the aquarium becomes cloudy, and the reason was an excess of light, you must darken the aquarium. If the lighting is not enough, you need to add it. It is possible to halt the excessive growth of algae. To do this, snails or fish that feed on algae and excess vegetation will settle in the pond.

What else makes the water in the aquarium cloudy? Because of the low-power filtering system. A prerequisite for the preservation of biological balance and decent maintenance of the aquarium is the presence and normal operation of high-quality filters. If the aquarium is dimmed after all, you can add a special additive, which is sold in specialized stores. However, in most cases, the balance in water cannot be restored.

To understand why the water in the aquariums becomes cloudy, you need to understand the reason for this process. However, it should be remembered that the water in the "pond" is always alive. Her condition is a consequence and the result of the interaction of a whole series of tiny creatures, therefore, certain conditions and time are needed for restoration. But hasty and wrong decisions can lead to even greater destruction, so you need to act carefully.

Why does the water grow turbid in the aquarium?

Muddy water in the aquarium This is one of the most common problems experienced even by aquarists. The reason for the violation of biological equilibrium can be a bacterial outbreak, improper feeding of fish, replacement of water in the aquarium and other factors. In some cases, it is enough to eliminate the cause, and after a few days the balance will be restored. But sometimes the turbidity of the water in the aquarium can lead to the death of fish and plants. In any case, first of all, it is necessary to establish why water grows turbid or blooms in the aquarium. And, only on the basis of the causes of violations, will it be possible to take any action.

Why does the water grow turbid in the aquarium?

When starting the aquarium for several days, there is a bacterial outbreak caused by excessive multiplication of single-celled organisms. Therefore, it is not recommended to settle fish immediately after launch. It is necessary to wait until the balance is established and the water becomes transparent. At the same time, changing water is also not worth it. A change of water will only cause it to become cloudy again. Usually, fish are settled in 5-7 days, and in order to speed up the process of restoring biological balance, it is recommended to add water from the old aquarium.

Turbid water in the aquarium can be the result of overfeeding the fish. If the food is not eaten completely, and settles at the bottom, the water will quickly deteriorate.

Also, muddy water in the aquarium may indicate poor filtration. With a large number of fish, you need to think very well about the water purification system, otherwise very soon the fish will start poisoning with decay products, which can cause the death of the inhabitants of the aquarium.

Why is the water in the aquarium green?

The flowering of water is due to the rapid growth of microscopic algae. This may be caused by an excess of light or accumulation of organic matter at the bottom. With a lack of lighting algae begin to rot and turn brown. If the water in the aquarium is cloudy and smells, then the cause may be the reproduction of blue-green algae.

What to do if the aquarium muddy water?

First of all, of course, you need to eliminate the cause of turbidity. If the problem lies in overpopulation of the aquarium, then you need to either increase water filtration or reduce the number of fish. If at the bottom of accumulated remnants of food, you need to reduce portions, and you can also settle the bottom fish that eat food settled on the ground. When flowering you need to darken the aquarium, if there is an excess of lighting, or vice versa - to install a more powerful lighting system with a lack of light. To prevent excessive algae growth, it is recommended to make fish or snails that eat excess vegetation. It is also worth paying attention to the filtering system. Наличие хороших фильтров – обязательное условие для содержания аквариума и сохранения биологического равновесия. Иногда рекомендуется добавлять в воду специальные добавки, но большинство аквариумистов не поддерживают такой способ восстановления баланса. В любом случае необходимо понимать, что живая вода в аквариуме – это результат взаимодействия множества живых существ, поэтому для восстановления баланса необходимо время и определенные условия.Incorrect actions can lead to even greater disruption, so the main task is to create conditions for stabilizing the balance.

How often do I need to change the water in the aquarium?

Proper replacement of water in an aquarium plays an important role in maintaining balance. A common mistake is too frequent replacement or replacement of a large amount of water. With a small litrazh such errors can result in the death of the fish. Before you change the water in the aquarium, you need to check the water quality, acidity and temperature. With a large volume, it will take about 2 days to restore balance; with a small volume, water needs change very carefully. After starting the aquarium, the water cannot be changed for 2-3 months until the balance is established. Subsequently, every 15-30 days replace up to 1/5 of the total volume. With a good filtration system and a small amount of fish, water is changed less frequently and to a lesser extent. If you replace more than half of the water in the aquarium, then the whole formed environment, including fish, may die.

In order to avoid problems, it is worth taking care of the proper equipment, starting and settling the aquarium from the very beginning. If you follow all the rules, it will not be difficult to achieve and maintain biological balance, and caring for an aquarium will not cause problems.

Why does the water in the aquarium smell like swamp?

With the help of an aquarium your home will be filled with beauty, comfort and warmth of exotic water bodies. Aquarium is a great place to observe beautiful fish and calm meditation. However, a damaged tank can ruin both your mood and the health of its inhabitants. Sometimes the water goes out and it stinks like a swamp. Muddy water spoils the impression, and makes the nursery unfit for further use. The problem requires an immediate solution, which involves finding out the cause and eliminating it immediately.

The main reasons why the water from the aquarium smells unpleasant, are indicated below:

  • Irregular cleaning of the tank or poor cleaning (filtration),
  • Improper aeration, because of which the water is not saturated with enough oxygen,
  • Unsuitable aquarium plants,
  • Nursery overpopulation - little water is allocated to one adult animal,
  • Overfeeding fish, reptiles or amphibians,
  • Feeding pets low-quality food,
  • The sudden death of the inhabitants of the reservoir, the body goes dead and decomposes,
  • The appearance of silt in the soil and water.

Muddy water that smells like a swamp - what to do?

If the aquarium fluid is worn out, which has strongly started to whine, and even smells like a marsh, it is possible to establish the causes of the imbalance of the aquatic environment through practice and observation. In the process of research, it will be possible to determine the method by which turbid water, which goes out and smells unpleasant, will be neutralized. To solve the problem should be phased actions.

  1. Decide whether you chose the right fish food. To do this, change the water, buy another, better food and test it in a few days. After a day, a cloudy liquid that smells like a swamp has disappeared and is clean, odorless, which means the cause of the problem was unsuitable food. In the case where the action did not lead to a result, other reasons should be sought.
  2. It so happens that you feed the fish and other animals with high-quality feed, but the aquatic environment is still muddy and "gives" the swamp. Probably, you overfeed the inhabitants of the nursery, and they do not have time to eat all the granules. Not all fish eat a lot, so arrange unloading diets for them, and add less feed to the water. A few days later sniff the tank - whether the unpleasant smell has disappeared. If yes, then you have found the reason. The uneaten food is mixed with the soil, decomposing.

Watch a video on how to feed the fish properly.

If you are a beginner aquarist and for the first time launched an aquarium, due to lack of experience you could create the wrong neighborhood in the nursery. It turns out that not all types of fish, snails, amphibians and reptiles get along together. Some will disturb others, and because of close space, someone will fall ill and die, quietly sinking to the bottom. Due to severe stress, insufficient shelters and swimming, the inhabitants of the reservoir excrete feces with a characteristic aroma. After a day or two there will be muddy water with a stench. What to do - get a spacious tank, pour water there suitable parameters, and settle there compatible pets. Or buy two aquariums at once, if many species are incompatible within the same space. Also carefully inspect the bottom - maybe one of the fish died, and the body is still not removed.

  • Wrong decorations can "decorate" the aquarium with an unpleasant smell. This is not a perfume, and living shoots, she has her own life. In this case, contact a specialist (the seller in the store or botany), and ask whether the purchased plant is able to allocate flavored vapors. Specify the size of the tank capacity, type of soil and water parameters. Replant the plant in the right environment - it may need a larger or smaller aquarium.
  • When the fish behave excessively actively, try to lie down on the bottom - the reason for the incorrect supply of oxygen, impaired work of aeration. To fix the equipment, you must:
    • install a high power compressor
    • replace the filter with a new one, with a forced circulation system,
    • Ask a specialist how to adjust the oxygen supply at an acceptable level.

    In the aquarium, the liquid is rotting and the marsh stinks - how to clean the water?

    Did you find out why the aquarium stinks, but you are not exactly sure what to do? Proper cleaning of the fish nursery is your main assistant! When all of the above tips have not led to the expected result, you will have to make a new plan to save the reservoir and its inhabitants. It consists in the correct cleaning of the container from harmful impurities and parasites, which are the main causes of an unpleasant smell. Before capital cleaning prepare such tools:

    • at least 5-10 liter jars with infused water of proper parameters for the temporary settlement of fish,
    • net, scraper and sponge,
    • big bucket
    • thermometer,
    • special liquid to remove contamination from aquarium glass (available in stores),
    • aquarium pump,
    • pH adjuster.

    Remove all animals from the nursery with a net by placing them in a jar of water. Disconnect the tank from the supply of current, light, turn off the filter and aerator. Rinse and clean the sponge. Use a scraper and a sponge to clean the windows, removing plaque, algae and other droppings from them. Take the pump, lower one end into the bucket, the second into the tank with dirty water, then pump out from 20 to 50% of all water, depending on when it was last changed. Put gauze on the pump, and run it along the bottom of the ground; the air will make a bottom siphon. After cleaning, remove all decorations.

    The scenery should be pulled out and processed, leaving them in a separate container with a little salted water (1 tsp per 20 liters) or scalding them with boiling water. If plaque forms on them, scrape it off with an unnecessary toothbrush or gauze. After processing, place the decorations on a clean cloth to dry, then reinstall in the aquarium.

    Pour into the aquarium a new, clean water of the same parameters that fish and plants are used to (temperature, pH, hardness). Infused water should be three days for chlorine to evaporate from it. Polish the outer glass of the tank (liquid for aquarium glass), and then reconnect all the devices. After the procedure, gradually run the fish. Cleaning can be done in a few hours, the main thing - to adhere to accuracy.

    Experienced breeders strongly advise settling in the nursery of the “orderlies” of the reservoir - freshwater snails, speckled catfish, mollies, antsistrusov, gyrinoheyls, labo, Japanese pond shrimps. The fishes living in the lower layers do an excellent job with the uneaten food that fell to the bottom, the snails eat carrion, and the shrimps and other fish mentioned above do an excellent job with algae. When settling you should take into account compatibility with each other, then your aquarium will resemble a natural biotope, with crystal clear water and beautiful living creatures.

    Bacteriological explosion ... Make a replacement of 1/3 of water, replace the sponge in the filter, clean the walls, the bottom is good, do not feed the fish for 3 days or at the minimum, turn off the backlight and the heater by 25 degrees. Gradually, everything will come back to normal.

    I get cloudy from overfeeding.
    I fight this way: siphon the ground thoroughly, topping up the water (50 liters of aquas somewhere I pour 7 liters fresh), letting it stand for a couple of days and once again the ground is siphon and topping up. between the siphons I feed the fish only with live moths from tweezers so that nothing falls on the ground. After the second siphon on the second day the water is crystal clear.


    Little info. What is the volume, when was the launch, who lives, dictation, soil, plants, ext. devices (filter, heater, CO2 regulator, compressor), what and how to feed, when was the last time the water changed and how much did the soil siphon?

    The water in the aquarium becomes cloudy from the appearance in it of a large number of putrefactive bacteria, which are very harmful not only for fish, but also for aquatic plants. The reason for the appearance of such bacteria is improper feeding and overly dense landing of fish in the aquarium. For good filtration of water, coarse-grained, cleanly washed river sand should be poured at the bottom of the aquarium, preferably in a dark color, with a layer of 4-5 cm. A full change of water in the aquarium should not be carried out, it is only necessary to periodically remove the dirt from top up with fresh water of the same temperature.
    The main trouble is due to improper feeding. It is necessary to ensure that any food is eaten in 30 seconds - 1 minute: the constant presence of food at the bottom of the aquarium is unacceptable.
    Many novice aquarists when cleaning an aquarium of a small capacity completely replace water in it, replanting fish and removing plants. At the same time, fish are injured and plants spoil. Often you can hear the full disappointment statement: "The more often I change the water, the more it grows turbid." This is true.

    In the newly equipped aquarium in the first few days, the water may be muddy due to the strong reproduction of single-celled organisms. After the aquarium is prepared and filled with water, you should be patient and do not rush into stocking it. As a rule, on the second or third day, the water in the aquarium becomes turbid, as if a few drops of milk were dropped into it, because after a complete replacement of water, after some time, microorganisms are usually rapidly developing, brought to the aquarium with fish and plants, and the water becomes cloudy. from the trash particles, and from the ciliates, the so-called "infusor turbidity" arises.
    In an overpopulated aquarium, turbidity in the water can occur, especially if there are few plants in it and the water is not blown or filtered. In such an aquarium, accumulated metabolic products serve as a good nutrient medium for the mass reproduction of bacteria and single-celled. In this case, you need to quickly precipitate extra fish. If the situation is not corrected in time, it can lead to disease and even mass death of fish, not to mention that such an aquarium looks ugly.

    Fish digging in the ground can also cause water turbidity. Such turbidity is harmless, and it is easy to eliminate it by increasing the top layer of purely washed sand at the bottom of the aquarium.

    Why does the water grow cloudy in the aquarium? even when changing water. what to do.

    when changing water, it becomes cloudy even faster, since new bacteria appear - this is the peak of their reproduction. Also, dry food can cause turbidity and generally bad microflora in the water - that is, the lack of “orderlies” - catfish, snails, soil, plants.

    Water needs to be changed, depending on the volume of the aquarium, from the calculation - how much was cast - so much was refilled, but not more than 1/5 and not more often than once every 2 weeks. The more often you change the water - the more it becomes cloudy. The mixing of water after its replacement is a normal phenomenon (its own microflora is settled there). Stop feeding fish of day 3 (they only benefit) and do not add lighting.


    Itself faced this problem. In addition to turbidity, the fish were inactive.
    Changing the water gave nothing. Then all friends moved into a bucket. Washed aquarium with SODA. Boiled stones. Filled with water, let her stand for 12 hours. Added fluid to run the aquarium and another 3 hours the water was settled. The filter worked. Launched the fish. (Catfish, guppies, barbs, cockerel)
    Now I do the water change 1/3 per week. And there are no problems at all.

    Why is the water in the aquarium muddy and stinks?

    Just do a lot of reasons why spoil the water. Improper lighting. Too much food. Throw in the water, the absence of filters in the aquarium. Bacteria, etc.
    For the night, the aquarium should be well treated first, then cleaned with boiled salted boiling water, all boiled thoroughly boiled in salt water, the algae should be examined if there are no diseases of the algae should be bright green and not damaged; New to heal you need knowledge and you, I suppose a newcomer to this, fish should be fed no more than once every 3 days and the food that you feed should be eaten in a minute and not set on the bottom of the aquarium and rot ...
    after treatment, water must be poured at least 24 hours. not less ..
    Go to the pet store buy means Akutan is a blue liquid, add it to the water at the rate of a cap of 10 liters. and after running the fish for 3 days the water will have a slightly white color turbid but within 3 days it will change. and the aquarium should be in a dark place but have a good daylight lamp. and do not forget about the number of fish at the rate of 1 fish 3-5 liters of water Ie per 10 liters of water not more than 2-3 fish of average size .... if possible, the filter of the pump should stand; water should circulate and be cleaned constantly; good filters have cells for adding coal to ceramics; well, they will tell you about this in the pet store, and good luck, and if so, ask.


    Apparently, either pour water not previously separated, or algae are bred there.
    With algae can fight. There are water snails that devour them.
    And be sure to plant a ragweed into the water - sold on the market. A plant that protects water from "dirt."


    Perhaps the filter does not work well or something got started there, that it is difficult to remove just by changing the water. These can be algae (small ones at all) and then you need to buy in the pet store a means to combat such algae. Or just try again not just to change the water, but even to boil the soil and to scald everything that you have installed in the aquarium


    damn, well what are you ?? ? Why change the water then ?? ? it is so necessary! You see, you probably planted plants there, so from the plants of day 2, the water must grow cloudy, and then everything will pass !! ! and do not change the water so often. it is generally very rarely changed, and then the fish will die ... everything is fine with your aquarium


    maybe you have a lot of fish and the aquarium is small. on 1 liter of water 1 small fish approximately. Try boiling pebbles all, maybe there bacteria have bred and multiply very good. quickly, water poured into the aquarium. but in general the smaller the aquarium, the more worries with it !! ! It very often needs to be washed. but if it becomes cloudy in one day, then you need to look for the cause, and the fish do not die.

    In the aquarium, fish need oxygen, a water filter, and even the water does not like a lot of light (it starts to bloom).
    If there are pebbles and shells, they should be boiled, water should be boiled, and water should be re-boiled and boiled for 2 hours, the aquarium should be washed with soda, the plants should be washed thoroughly. Before you pour water into the aquarium, you need to defend the water for 3 days, then pour it into the aquarium, then put oxygen into the water and after 20 minutes you can let the fish.

    Aquarium should be at least 25l. Otherwise, it will not be an aquarium, but crap! There necessarily need a filter and pump (bubbles). Sunlight should not be on the aquarium. Fish should be fed 2-3 times a day in small portions. Water changes no more than 30% at a time. Immediately start the fish can not be! It is necessary to first establish a biobalance. (about 4-5 days). Generally dig a good internet! you probably first have fish, then an aquarium, then plants, and then food. all the way around!
