Why the water in the aquarium dimmed


Muddy aquarium: from what and why the water becomes cloudy, what to do


problems of whitish, green, brown water

Turbidity of the aquarium is a frequent occurrence in new, just-launched aquariums. However, "aquarium murk" does not bypass the already established "old" reservoirs. On the Internet, a lot has been written on this issue. There are lots of articles and even talmudov about the turbid state of aquarium water. However, a significant drawback of these articles, in my opinion, is the lack of practical recommendations for eliminating turbidity and its causes. Yes, theory is good, but what to do? How to get rid of turbidity? What preparations should be used in a given situation, what actions should the aquarist take to make the aquarium beautiful and the water truly clean?
We will try to answer all these questions in this article.
So, the reasons that the aquarium water has become muddy are:
- mechanical factors;
- biological factors;
theory, reasons, ways to eliminate
Aquarium water is a closed ecosystem, where there are various artificial elements that recreate the natural conditions of fish habitat. As well as in nature, water in the aquarium may cloud due to the large number of small suspended particles that were lifted from the bottom of the aquarium, separated from the scenery, formed as a result of the livelihood of aquatic organisms (all aquatic inhabitants).
It can be said that the mechanical clouding of the aquarium is trivial, in fact, it is the dirt and debris of the aquarium, which arose as a result of laziness or proper, improper care for the aquarium.
Let's take a closer look at the reasons for this action:
Errors made when starting the aquarium. Usually the launch of the first, new, just bought aquarium, occurs in a euphoric state. A beginner in a hurry puts the aquarium in a hurry, pours in the ground there, sets the decor and fills it all with water.
Alas, such a rush, later does not well affect the appearance of the aquarium. Water appears in the water, which has not previously been washed away or washed from the scenery and the ground. This is especially true of the ground. Before you lay it on the bottom of the aquarium, it should be washed thoroughly and more than once. Otherwise, dust and small particles of soil will "spread out" throughout the aquarium.
Not the right or inappropriate care. As a result of the vital activity of fish, plants, crustaceans and other inhabitants of the aquarium, waste is generated: feces, food remains, dead organics.
If proper, regular maintenance or filtering of aquarium water is not properly set up in the aquarium, all these residues accumulate. And eventually they begin to swim throughout the reservoir. Moreover, the residues gradually decompose, which gives prerequisites for biological clouding.

The use of "not correct" decorations in the design of the aquarium.
As the decoration of the aquarium can not use bulk, soluble and coloring objects. All these objects will sooner or later be washed out or dissolved by water, which will lead not only to a violation of the aesthetic appearance, but also threatens with chemical poisoning of all living things in the aquarium.

Ways to eliminate mechanical turbidity in the aquarium

Naturally the first is a thorough cleaning of the aquarium with the replacement? aquarium water to fresh, plus siphon aquarium bottom and cleaning the walls of the aquarium. Extract all the "bad" decorations.
The second is the enhanced filtration of aquarium water. The existing filter is cleaned and washed, re-installed. Plus, another new filter is installed or a more powerful filter is bought to replace the old one.
Tip: Mechanical turbidity in the aquarium is very fine. Under the influence of any oscillation (excitement), it sweeps up and heaves. Before the general cleaning of the aquarium, it is recommended to turn off aeration and filtration in the aquarium for 2-3 hours, a little more. In the absence of generated water currents, all small particles floating in the water will gradually sink to the bottom and aquarium decorations. After that, they will be easy to collect siphon.

Preparations eliminating mechanical turbidity in an aquarium

Aquarium coal - Absorbent, perfectly coping with pollution of the aquarium. Coal is poured after cleaning the aquarium in the filter compartment and held there for two weeks. After that, a new portion of coal is removed and, if necessary, poured.
TetraAqua CrystalWater (drug TM "Tetra") - binds small particles that are in the water and combines them into larger ones, which are then either removed through a filter, or are deposited on the bottom. Such a course of the cleaning process is guaranteed for any kind of filter.
If small particles still float in the water, these may be food remnants, with over-feeding, or particles of soil that have risen after changing water.
The product acts on both the physical and chemical levels. The first results are noticeable 2-3 hours after application. After 6-8 hours, the water becomes clean, and after 6-12 hours - crystal clear. Dosage: 100 ml per 200 l of aquarium water.
Tetra Crystal Water is recommended even with a slight clouding of the aquarium, it is very useful to use the drug before the photo session of the aquarium. In practice, the period of complete water purification can stretch for 2 days. Most likely it depends on the degree of pollution of the reservoir.

Sera aquaria clear
(similar to the previous drug, but from TM "Sulfur") - a means for removing contaminants from aquarium water, quickly, simply and reliably connects the "dregs" of any origin in aquariums.
Bound "turbidity" is removed using a filter installed in your aquarium within a few minutes. Sera Aquaria Clear - acts biologically and does not contain harmful active substances, effectively removes contaminants from the aquarium water.
theory, reasons, ways to eliminate
Aquarium water is not sterile. Even when the water visually looks perfectly clean, it contains various microorganisms and fungi that are not visible to the human eye. And this is the normal state of affairs.
In our world, everything is interconnected; everything that was invented by God is not superfluous and is needed for something. Fungi and bacteria (good or bad) in aquarium water play a crucial role for all other inhabitants of the aquarium. Fungi are involved in the decomposition of dead organics, bacteria recycle ammonia, nitrites and nitrates (aquarium poisons), etc.
Now imagine what happens if this process is disrupted? That's right, there will be murkiness! Such a violation in akvaraimistiki called "biobalance violation" or "biological equilibrium."
By the time of flow, the biobalance violation can be divided into:
Violations in the "young" - a new, just-launched aquarium;
Violations in the "old" - well-established aquarium;

dimmed water in a newly launched aquarium

In many sources on this issue it is very briefly written: "Do not worry, the clouding of your aquarium will pass by itself in 3-5 days." And the point! After reading this, the aquarium novice exhales, says "Fuv, thank God" and calms down on it.
But, with this position we can agree only partially. Yes, indeed the first 3-5 days of the newly launched aquarium will be muddy. Then whitish cloudiness, similar to fog or colostrum (sometimes with a brownish or greenish tinge) disappears by itself. But, as mentioned above, “aquarium water is not sterile,” and the absence of turbidity does not indicate that the problem has been solved.
What happens in a young aquarium? Why does the water in the aquarium grow turbid?
In short, in the aquarium there is a setting of biological balance. Namely, there is a rapid growth of bacteria, fungi and other unicellular microorganisms. At the same time, products of life of fish and other inhabitants of the reservoir accumulate in the aquarium. Not joining of the two leads to their excessiveness, which is manifested visually in the form of turbidity of water. Gradually, the process is aligned and the biological chain closes. In other words, the amount of food (dead organics, fish food residues, feces) is equal to the number of colonies of beneficial bacteria, and of fungi, which they eat and decompose into smaller “elements”.
Based on the above, we can agree that the clouding of a young aquarium is not so scary. But, it can be prevented! Or rather help the aquarium tune faster. How? We will talk about this a little later.

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 an old aquarium include “whiteness after fish treatment”, 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. The following happens: under the influence of non-excreting poisons, the fish’s immunity weakens, their defense mechanisms weaken and become unable to resist the “harmful” - pathogenic bacteria and fungi (which are always in the water). As a result, the fish gets sick and if you do not conduct treatment in time, the fish dies. Thus, we can conclude that the violation of biological balance is the primary cause of the death of aquarium fish. In fairness, it should be said that the saturation of aquarium water with excess ammonia, nitrite and nitrate - can occur without turbidity of the 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 to fresh water is an effective way to get rid of poisons.
ATTENTION: To replace the 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 generally needs to be tried less often 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. Also effective as a disinfectant disinfectant and medication remover.
At the same time, it is capable of even more: it binds toxic heavy metals such as copper, zinc, lead, and even mercury. Therefore, these pollutants can not harm the fish and beneficial bacteria in the biofilter. Due to this, the frequency of water changes can be reduced.
If necessary, for example, with particularly high levels of contamination, an increase in the applied dose of the agent is allowed. Repeated depositing is allowed in one or 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 that are weakened or damaged by the use of medicines.
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 in water. The drug eliminates the nutritional element necessary for the development of algae, which allows for a long time to improve water quality, reducing, thereby, the need for care of the aquarium.
- lowering the level of nitrates by 12 months by biological means.
- significantly algae growth is 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 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. При регулярном использовании препарата после замены воды, стабилизируется показатель воды pH и снижается риск падения кислотности .
Полная совместимость, NitrateMinus основан на биологических процессах в аквариуме и полностью безопасен для рыб. Он прекрасно сочетается с TetraAqua EasyBalance и другими продуктами Tetra.
Sera bio nitrivec (Sera bio nitrivek) - A preparation 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 makes it possible to place the fish in the newly created aquarium already 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 aquarium water.
There are other drugs of identical orientation. I recommend sharing Tetra Bactozym and Tetra NitranMinus Perls.
And when using NO2NO3 flashes, use zeolite.

How else can you achieve a “good biobalance”?

- Biological equilibrium is more stable if live aquarium plants are present 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. "Squad" of the same coil snails copes with dying leaves and organic matter. 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 to improve water quality, for example, phyto filtration.

What to do if the water in the aquarium dims

Novice aquarists often encounter the phenomenon of clouding the water in an aquarium. This can happen for various reasons and it is important to know how to solve this problem quickly, so as not to harm its inhabitants.

The question "HOW baby to retrain to go to the tray (she is 4 months)?" - 3 answers

Some newcomers are in a hurry to equip their first aquarium and populate it with fish. Therefore, after a few hours, the water becomes turbid with a whitish tinge. This is due to the violation of the biological balance - the number of bacteria increases dramatically. Water must first go through a period of "ripening". To do this, you first need to plant aquarium plants, pour the water that has settled for two days and leave the aquarium for several days. During this time, the water will become transparent, sometimes slightly greenish. Biological balance will be restored and now you can run the fish.

In some cases, and in a long-functioning aquarium, the mass reproduction of bacteria begins, this happens when there are a lot of fish and the aquarium is not cared for. In this case, you should do a general cleaning. Sow the fish in another container, clean the soil, remove excess plants, replace the water and wait a few days until the water is clear - the balance will not return to normal.

Sometimes water can become cloudy if you give a lot of dry food. Fish eat it poorly, the remnants begin to rot, which contributes to the proliferation of bacteria. Therefore, it is recommended to switch to the use of live food, for example, bloodworms. It should be given at the rate of up to 5 pieces per medium fish. Also great help in the destruction of uneaten remnants of food provide snails, but their numbers also need to be controlled.

Under the wrong light, the water may turn green, become muddy, and a raid appears on the glasses, plants and decorations. This is due to the rapid increase in the amount of algae. In such cases, make the replacement of the third part of the water 1 time per week, run the fish that eat algae, strengthen or, conversely, reduce the lighting. Be sure to turn on water filtration. Remove plaque from windows with a special scraper.

The problem of turbidity is easier to prevent than to eliminate. Therefore, follow a few rules:

- do not change the water in the aquarium completely, except for emergency measures;
- adjust the amount of feed, normally it should be eaten by fish for 10-15 minutes;
- Watch the number of fish in the tank, do not allow overcrowding;
- regularly replace water;
- Do not forget to remove overgrown plants, clean the soil and filter the water.

Causes of water turbidity and how to deal with it

Muddy water in an aquarium is a common phenomenon that almost every aquarist has encountered. Sometimes the causes of the problem are found quickly, and sometimes it takes a long time to figure out why the water has become cloudy. How to deal with the formation of turbidity, what is recommended to do and what is not?

When does water appear in the water?

The causes of muddy water in an aquarium can be varied, and it is not as easy to deal with them as it seems at first glance.

  1. Turbidity can occur due to swimming in the pond of small particles of algae, solid organics and cyanobacteria. There is another unobtrusive reason - poor washing of the aquarium soil and inaccurate pouring water from a clean tank. This type of turbidity does not threaten the water and the fish, you can do nothing with it. After some time, the muddy part of the water will settle, or seep into the filter, remaining there. The formation of turbidity can provoke fish who love to plow the ground, but these actions for the reservoir are completely harmless.

  1. Turbid water in an aquarium can be caused by cichlids, goldfish and tail finch fish - their active movement in a reservoir is the cause of the resulting turbidity. If a filter is not installed in the tank, it will be difficult to clean the water.
  2. Often, muddy water appears after the first start of the aquarium, after the fresh water inlet. Nothing to do, in a day or two the sediment will fall to the ground and disappear. The mistake of novice aquarists is a partial or complete renewal of water, which is considered a gross error. When adding new water to a newly launched aquarium, the bacteria will become even more! If the aquarium is small, you can install a sponge filter that quickly cleans the pond.

Watch the video about the device and the operation of the internal filter.

  1. Malicious bacteria in an aquarium can also be causes of turbidity. When the water becomes green, then it's time to draw conclusions - this is an unnatural color. Muddy and green water is formed due to overcrowding of the aquarium with fish or plants. That is, the aquarium fluid passes through the filter, but is not cleaned. The abundance of metabolic products provokes the formation of putrefactive microorganisms, ciliates and other unicellular. If ciliates are beneficial, the bacteria can harm the plants - they will start to rot. In order not to be surprised why fish and plants often get sick - watch the aquarium clean and tidy.

  1. Why still breed single-celled? Because you do not have time to clean the tank after heavy feeding. For aquarism it is better to underfeed than to feed. This rule will protect the fish from problems. After overfeeding again the water got cloudy - what to do? Arrange a pet unloading diet for a couple of days, the bacteria will die out, the water biobalance will be restored.

  1. Incorrectly installed decoration. Snags, plastic materials of poor quality dissolve in water, forming a muddy shade. If the scenery is new wooden, but untreated - they can be boiled or infused in salt solution. Plastic snags should be replaced by new ones.
  2. In the old, stagnant nursery with fish sediment is formed due to "whiteness after fish treatment", this is when drugs and purification chemistry for aquarium glass were used in the pond. Such substances have a number of side effects, they disrupt the biological equilibrium, neutralizing the favorable microflora.

How to overcome turbidity in water?

Now we know the reasons why the water grows cloudy in the aquarium, and what to do in each case. However, there are general rules, without which it is impossible to completely eliminate the problem.

  1. Siphonte the soil in the aquarium. Open the filter, rinse and clean. Then add activated carbon to it - this needs to be done to absorb harmful substances. It is forbidden to make a complete replacement of water and washing the aquarium soil, otherwise the beneficial bacteria will die out and will not be able to process rot and algae.

See how to siphon the soil in the aquarium.

  1. In some cases, it is necessary to do an intensive aeration of the aquarium - when there are a lot of fish feed residues and a fasting day is not enough. Oxygen will quickly remove excess organics.
  2. If an unpleasant smell disappears in an aquarium, it means that the struggle with mist is over successfully. Also for elimination of bacterial turbidity it is possible to use elodeya, having landed it superficially in a ground.

Dregs in the water: types

The color of turbidity will tell about the sources of its formation:

  • The water color is greenish - single-celled algae reproduce;
  • Brown water - peat, humic and tannins, poorly processed snags;
  • Milky white color - unicellular bacteria begin to multiply;
  • The color of the water coincides with the color of the soil or of a stone recently laid on it, which means that the soil was plowed by fish, or the stone turned out to be weak.

Drugs that prevent the appearance of turbid sediment

  1. Aquarium coal is absorbent, which is added after cleaning the tank to the filter for a period of 2 weeks. After extraction, you can fill in a new batch there.

  1. Tetra Aqua CrystalWater is a tool that binds small particles of dirt into one, after which they can be removed or passed through a filter. After 8-12 hours the reservoir will be crystal clear. Dosage - 100 ml per 200 liters of water.
  2. Sera Aquaria Clear - also binds sediment particles, passing it through the filter. During the day, dirt can be removed from the cassette. The drug does not contain harmful substances.
  • Before adding sorbents to water, it is better to move the fish to another container.


In order to avoid turbid water, it is necessary to control the level of nitrates, nitrites and ammonia. They stand out as a result of the vital activity of fish, plants and improper care of the water body. Therefore, fish should be settled in the tank, the size of which corresponds to its volume. Proper feeding of pets, timely cleaning of the products of their vital activity, removal of rotten plants will settle the water balance. If there is no mechanical or biological filter in the aquarium, replace 30% of the water weekly with fresh and sedimented. Do not add water from the pipeline with the smell of chlorine or boiled.

Why does the water grow turbid in a fish tank?

The aquarium is not only an interior decoration, but first and foremost an ecosystem that lives according to the laws common to all ecosystems. It is stable when there is a biological and chemical equilibrium in it. An imbalance immediately affects the appearance of the aquarium, and primarily the quality of the water.

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

Why does the water grow cloudy?

Turbidity in the aquarium is usually caused by the massive development of various bacteria. Where do bacteria come from? They, like other microbes, enter the aquarium with fish and plants. Their source can also be soil, fish food and even air with which water is in contact. A certain number of bacteria is always present in each of the elements of the ecosystem. In a certain amount, they are harmless to other inhabitants of the aquarium. At the same time the water remains clean and clear. With the mass reproduction of bacteria, you will definitely encounter two or three days after filling the aquarium with fresh water. This is due to the fact that in the absence of a sufficient number of other organisms, bacteria begin to multiply rapidly. Outwardly, it looks like a light whitish or nacreous homogeneous dregs. The process of reproduction of bacteria goes faster if there are plants and soil in the aquarium.


After another 3-5 days, turbidity disappears. This is due to the appearance of ciliates in the aquarium water, which are intensively eaten by bacteria. There comes a moment of equilibrium of the ecosystem. From this point on, fish can be settled in the aquarium. Plants need to be taken from an aquarium with healthy inhabitants.

Organic slurry

The clouding of the water in an aquarium where there are already fish can be caused by an organic slurry. The suspension is formed from the waste products of fish and plants, as well as improper feeding and an excess of dry food. To control the suspension, aquarium filters are used, including biological ones, in which organics are actively absorbed by bacteria living on the filter material. Mandatory measures are also cleaning the bottom, removal of dead parts of plants, dead organisms, excreta.

Imbalance in the presence of fish

The rapid turbidity of the water in an aquarium with living fish can be a manifestation of an imbalance and may be the first symptom of the disease of the entire ecosystem. For example, precede the blooming of water. In this case, the aquarium has a large volume, frequent full change of water in it is impractical. It is easier to restore biological balance by adjusting the light mode and replacing only part of the water. In large aquariums, biological balance is easier to maintain than in small ones, but it lasts longer. Branching crustaceans (daphnias, moinas, basmins, etc.), which feed on bacteria, are good feeds for fish are good sinkers of dregs. A mandatory equilibrium factor should be considered aeration and filtration of water. Filters should be cleaned regularly.

New aquarium and fish. Why is the water dimmed? how to deal with it?

Yury Balashov

Aquarium is new, then you need patience to make tap water aquarium. While the aquarium is running, do not change the water, do not turn off the filter, feed the fish for 2 minutes. c "ate all the food, turn on the light, a maximum of 6-8 hours, etc., etc., etc. Good luck.

cat Basilio

Water clouding can occur for various reasons; it is not always easy to deal with this phenomenon. In the most harmless case, the water becomes cloudy due to small particles of soil suspended in it, for example, after careless pouring water into the aquarium. Such clouding does not have any unpleasant consequences and after a while disappears by itself when the turbidity settles to the bottom.
The water in the aquarium becomes cloudy with the appearance of a large number of putrefactive bacteria in it, 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. One of the first rules in aquarism: it is better to underfeed than overfeed. If you follow this rule, you will get rid of many possible problems in advance.
In the newly equipped aquarium in the early days, the water may be muddy due to the strong reproduction of single-celled organisms in it. After the aquarium is prepared and filled with water, you need to be patient and do not rush into stocking it. It happens that on the second or third day, the water in the aquarium becomes muddy, as if a few drops of milk were dropped into it, because after a complete replacement of water, microorganisms usually develop rapidly after some time, and the water grows cloudy not from the weed particles, there is a so-called "infusorial turbidity".
The rapid reproduction of bacteria can manifest itself in your aquarium every time you replace a large amount of water, and also in those cases when you forget to remove the remnants of uneaten food or decaying plants from the aquarium in time. Such clouding, if you eliminate its cause and wait a while, passes.
In the aquarium constantly occur interrelated chemical and biological processes, as a result of which some animal and plant organisms are born, while others die.
A huge mass of bacteria that lives in the water column, in the soil and in the filter filler processes the decay products and the vital activity of plants, food remains, fish excrement. Bacteria are in turn food for ciliates, etc.
Water may become cloudy in an overpopulated aquarium if it is not sufficiently well blown or filtered. In such an aquarium, accumulated metabolic products serve as a good nutrient medium for the mass reproduction of bacteria and unicellular organisms. In this case, you need to quickly precipitate extra fish or improve the filtration system or purge. If the situation is not corrected in time, it can lead to a disease or even a massive death of fish, not to mention that such an aquarium looks very ugly.
-Full change of water in the aquarium should not be!
- It is necessary to monitor the proper nutrition of fish.
-Permanent presence of food at the bottom of the aquarium is unacceptable!
-In the first days in the re-running aquarium water can be muddy due to the strong reproduction of single-celled organisms.
- In an overpopulated aquarium, water turbidity may occur due to insufficient purging or water filtration systems.


go to any aquarium site, there are sure to have articles for beginners ... in the new aquarium (less than 2-3 weeks) there should be no fish, only water, which must first become cloudy, but then clean itself (different types of bacteria develop). while it is not necessary to change it!
if the aquarium is already settled, then the reason for the turbidity is likely to be overfeeding, then changing half of the water, and not doing that again; -)

Natalia A.

When starting a new aquarium at the start, a bacterial outbreak is inevitable, everything is fine with you, wait a few days, biological balance will be established and the water will clear itself, in no case do you need to change water, absolutely nothing to do, but wait. The only thing is that the fish were launched early, but you can and should feed them a little bit.

Marina Filippova

I agree with Natalya Abumova, as the director of pet-shop I can tell you too: the balance will be established by itself, the useful bacteria breed in the aquarium, and if there is one in the filter, so the water turns white. Wait a bit. In the future, in no case completely change the water in the aquarium completely, only partially, for example, in a 30 l aquarium, only 5 l of water should be replaced once a week with fresh settled water, otherwise each time new reproduction of beneficial bacteria and each time clouding and possible biotope population losses and even among the plants. If you don’t have time to defend water or want to improve the fish’s habitat a little, use air conditioners for aquarium water, ask your pet shop consultants for good luck in your endeavors!

Andrey Kovalenko

"If there is no time to defend water ... use air conditioners for aquarium water" "well, well, these are the words of the consultants that many newbies peck at, while buying a bunch of all sorts of fish (in the same store), come home and start up the aquarium and then the air conditioners in the aquarium (thinking that the biological balance has already been established) push many fish there at once, and as a result they get ...
but I especially liked this- "or if you want to improve the habitat of fish a little - use air-conditioners for aquarium water, ask about pet-shop consultants)" - sounds like an advertisement :)))
P.S. So my advice is to run an aquarium without any chemistry. (more quietly you will continue)

Hello friends. Today we will talk about such a moment as muddy water in an aquarium. This phenomenon is very common and many beginning aquarists are afraid of it and do not know the reasons for this phenomenon and how to actually fight it. In today's article I will try to shed light on this mystery and I hope that newcomers after reading this article will be as they say "in all weapons." And so, let's start to understand.
Turbid water in an aquarium can become for a variety of reasons, and sometimes it is not very easy to deal with this negative point. The main reason for which the water in the aquarium grows turbid is that small particles of solids, algae or bacteria float in it. There is still an innocuous moment of muddy water - this is if you have poorly washed the aquarium soil and have not carefully poured in some water after cleaning the jars. Here such turbidity does not represent any harmful consequences for your aquarium and after a certain time the cloudiness will partially settle, and partially fall into the filter and remain there. They can also raise the dregs of fish, crawling in the ground.
With the turbidity of the water in the aquarium, owners of aquariums often encounter voile tails, cichlids and goldfish, which constantly dig in the ground, plus aquariums in which there is no filter. Turbid water appears after the start of the aquarium, when you fill it with fresh water. Do not do anything with it, it is disgusting rose from the ground, it literally settles within 24 hours. A very common mistake of newbies - they, as they see muddy water after the start of the can, immediately begin to change it and refill it fresh and the process repeats. In the absence of a filter in aqua, the water starts to deteriorate rapidly, and it deteriorates more strongly in aquariums of small volume. Sponge filters will come to the aid of the aquarist.

Extremely worse impact on the aquarium has a murk of bacterial origin. If the aquarium is overpopulated and there are some aquarium plants, the water may become cloudy. Water is essentially only passed by the filter but not filtered. In this case, there will be a lot of metabolic products in the water, which will serve as an excellent food for bacteria and all kinds of single-celled. Also, the water may become turbid in the aquarium due to ciliates and various putrefactive bacteria that are abundantly distributed in such water. These reptiles are equally harmful to plants and fish. The main reason for the development of these bacteria is an oversupply of organic matter in the aquarium.
Another reason why the aquarium is densely populated with these single-celled ones is excessive feeding and overpopulated cans. Remember once and for all the golden rule of aquarism - better underfed than overfeeding. If you adhere to this rule, you will protect the inhabitants of the aquarium and yourself from excessive hemorrhoids from these problems. If, nevertheless, such a fate befell you, give better than extra fish to one of the aquarist's friends. In the case of cloudy water, do not try to feed the fish, so you will make it worse. It is better not to feed the fish for a couple of days, the bacteria during this time will die, and nothing will happen to the fish. Make it a massive fasting day :)

Here's another tip for you - if the water in the aquarium is still dimmed, you need to immediately correct the situation, or you will lose all the fish. Due to the stability of the bacterial dregs, the aquarist does not have time to think and expect such as “what if the water becomes transparent”. If you do not take the necessary measures in time, the situation may become critical, and it will not be easy to leave it. In advanced cases, there is sometimes no point in dealing with the turbidity of the water; it is only the complete replacement of water that helps to establish the biological equilibrium.

Why does the water in the aquarium cloudy ???


Why does the water grow cloudy?
There may be several reasons. In conditions when the biological equilibrium in the newly equipped aquarium has not yet been established, even a slight excess of food (dead alive or dropped to the bottom and plants dry) causes water turbidity due to the rapid development of microorganisms. Therefore, it is necessary to keep an eye on such an aquarium - give so much kurma that the fish eat it quickly, clean up the leftovers.
Excessive amounts of food can cause turbidity in the aquarium with established equilibrium. Bacterial murkiness happens in poorly prepared aquariums, where the ground is not thoroughly washed.
To get rid of such turbidity is possible only by establishing the cause. The enlightenment of water in aquariums contributes to a temporary break in the feeding of adult fish (up to 3-4 days), and food residues must first be removed.


This is a natural process. Do not drain the water. It may become like diluted milk, but in a couple of days everything will pass. A certain microclimate is established in water. For 5-6 days the water will be crystal clear.


There was no need to drain the water. And the fish should run in a week, not earlier! I am surprised to those sellers who have not understood why tablets. Better yet, get a biofilter with ceramic balls. On these balls settled beneficial bacteria and cope with harmful. This one could be done without those pills.


Your aquarium was originally started up incorrectly. Now there are two options: 1. Do not feed the fish or feed very moderately and replace 10 liters of water every day, so do approx. weeks can help. 2. restart the aquarium: wash everything, pour water from the tap, add anti-chlorine and bacteria, turn on the filter, you can run the fish in a day, feed very little.
excuse me, of course, but you had to first read how to run an aquarium, and then buy an aquarium. Fish can not withstand such treatment !!!

The reasons for the sea: 1) how it stands aquarium lighting Direct sunlight or excess lighting causes the appearance of green algae (the water turns green). The lack of light causes the appearance of brown algae (the water turns brown), 2) feeding adult fish is enough to feed once a day to lay so much feed that it can be gray in 15 minutes. Excess feed needs to be caught with a pipe. 3) the ground should be coarse sand or pebbles (better sand then the falling fish feed easily lift, it falls down under the stones) the sand is very coarse, otherwise it quickly becomes silted and begins to rot. 4) The filter should be sufficiently powerful to remove sludge (mechanical dirt) 4) do not overpopulate the aquarium (you do not like neighbors with you; they don’t like neighbors to enjoy the rest. water with soil we plant the plants; you can plant small snails and wait; the water will begin to grow cloudy. It becomes whitish. This is a crisis of overproduction of bacteria. We do nothing we wait if the water becomes lighter and after a while it becomes transparent, as a tear means biological balance has been established, you can plant fish. Or the water from the whiteness may turn into a green, caricnic or just muddy and smelly meaning there was a mistake somewhere and the balance was disturbed, one way out to repeat the new filling. But if everything is well the aquarium is clean and the fish are happy, then this is not all. Follow the above recommendations and do not change the water, but if they change it, only to imitate the rainy season and only 1/4 of the aquarium.
