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


PROBLEMS OF THE MUTT AQUARIUM

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;
MUTT AQUARIUM: MECHANICAL 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 begin to swim around 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.
MUTT AQUARIUM: BIOLOGICAL FACTORS
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 dregs! 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;
MUTTY YOUNG 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.
MUTT OLD AQUARIUM

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.
"DIRT AND TRASH"
(remnants of dead organics, fish food, feces, etc.)
decompose under the action of bacteria in
AMMONIA / AMMONIUM
(the strongest poison, destructive for all living things)
under the action of another group of bacteria is decomposed into
NITRITES, and then NITRATES
(less dangerous, but also poisons)
further decompose to
GAS STATE
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.

HOW TO GET RID OF BIOLOGICALLY DISTURBED AQUARIUM

or how to set up a 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 nitrates 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 that improve water quality, for example, phyto filtration.

Useful video about muddy water in the aquarium



Why does the water quickly grow turbid?

Muddy water in an aquarium with fish is perhaps the most common problem that concerns both beginners and experienced aquarists. Through trial and error, we have to figure out why muddy water appeared so quickly. The causes of this phenomenon can be different, ranging from a bacterial outbreak, improper feeding and irregular water renewal. A number of factors may also be the source of this problem. When the elimination or elimination of the causative agent of water turbidity in an aquarium occurs quickly, then the biological balance in the water is fully restored.

Sometimes this trouble provokes the death of fish, plants and invisible microorganisms. The first thing to do is to find out why the water becomes cloudy quickly. The second is to gradually eliminate the shortcomings.

Causes of Aquarium Water Turbidity

Why is the aquarium water quickly dimmed if the tank is equipped with a filter? The main problem is that on the very first day of the launch of the aquarium there is no holistic and permanent biological environment. The so-called "bacterial explosion" is caused by an active increase in the number of unicellular microorganisms that are constantly multiplying. In this case, the fish should not be settled, it is better to do it on another day. When microflora equilibrates in the tank, then the water will become crystal clear. Nothing serious needs to be done - this sediment will pass by itself. If you decide to change the water - it will again become muddy and unfit for life.

For 4-7 days the aquatic environment is fully restored, you can run plants and fish into it. To speed up the process, you can add water after the old aquarium with "residential" water.

Another common problem with the rapid turbidity of water in an aquarium is poor filtration of the reservoir. It should be well thought out system of purification, and this should be done quickly, until the young fish and did not have time to get used to a new house. A bad filter does not allow bits of dirt, feces, food debris, provoking the formation of decomposition products. Such rotten water constantly stinks and can cause diseases.

Watch a video about filtering water in an aquarium.

Why still water quickly becomes cloudy? If it has become an unpleasant green color, dimmed in a short time - it means that microscopic blue-green algae develop in it, which lead to the flowering of the reservoir. With good development of organic and strong light, they make themselves felt on the fifth day. When the light is not enough, cyanobacteria will acquire a brown color and begin to rot. Green color of the liquid with muddy, unpleasant smell - signs of growth of blue-green algae.


Aquarium water turbidity: action

If frequent water changes, the growth of bacteria and algae provoked the appearance of muddy water in the aquarium, some steps should be taken to eliminate the problem.

  1. If your aquarium is overpopulated, place the fish in different tanks, where they would be comfortable and spacious.
  2. If there is an excess of light, shade the aquarium by setting it in a secluded corner where strong lighting does not go.
  3. If the water becomes cloudy the next day after the first feeding, make a bottom siphon and feed the fish in small portions.
  4. Settle snails and fish in an aquarium that eat leftover food, clean glass and water in a tank. After a few days, the water will become free of dirt, and will not require additional replacement.


Wrong settlement of fish as a cause of rapid turbidity of water

Why 2-3 days after the settlement of fish water became muddy? The fact is that for every one liter of water in the tank it is required to settle only one medium fish. If you run more pets, there will be problems with the pollution of the "house". Some fish plow the ground, and if there are many such individuals, it will turn into an underwater hurricane. Immediately move the fish in different aquariums, provide enough space for them. It is also important that they have enough oxygen, shelters and plants. In poor water oxygen to the fish can get sick.

In the aquarium with proper care and the right equipment, the water on the second day will not deteriorate. After running the fish, make sure that it adapts to the new environment. For 3 liters of water it is necessary to settle the fish size of 3-5 cm.

If the water is cloudy, you can use drugs that purify water from turbidity and dirt. After using them, water changes in the aquarium are not required for a few more days. They connect all the small particles that spoil the water until they fall into the filter. The next day, the entire bacterial cloud, small algae settle on the filter sponge, after which they can be removed.

These are the drugs: JBL Clearol, JBL Clynol, Seachem Clarity, Sera Aquaria Clear.

Watch a video about water changes.

How to change the aquarium water?

Full replacement of water is required only in the rarest cases, for example, with general quarantine or water poisoning. Why not do this procedure often? Because the day after the complete substitution, you will notice how the water turned cloudy again. A significant loss of its volume is stress for all inhabitants of the reservoir. Even during the death of some fish do not replace the water. But there are a number of recommendations, after studying which it is possible to understand why substitutions are necessary.

  • Substitutions are necessary after the introduction of pathogenic microorganisms;
  • Replacements are required after visible flowering of the reservoir;
  • Urgent water changes are necessary when a fungal mucus is detected;
  • Renew water is required due to severe soil contamination.

You can add water to the tank as it evaporates, but not more than 20-30% of the total volume. It is best to update 1/5 of the aquarium once a week. After the procedure, the biocenosis will recover in 2 days. With the replacement of water cleaned the glass from plaque, remove debris from the bottom, clean snags and decorations.

It is better to plan a water change for both small and large reservoirs in advance. Type in a glass tank water from the tap, and leave it for a few days, covered with gauze. Chlorine and gas will evaporate, the liquid will be safe for fish. And it should be remembered that in the first week of operation of the aquarium the water is not changed until an ecosystem is formed in it.

Why does the water grow turbid in the aquarium?

Turbid water in the aquarium This is one of the most common problems that even experienced aquarists face. 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 an 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 clouded and smells, then the cause may be the reproduction of blue-green algae.

What to do if in 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 establish 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. The presence of good filters is a prerequisite for the maintenance of the aquarium and the preservation of biological equilibrium. Sometimes it is recommended to add special additives to the water, but most aquarists do not support this method of restoring balance. In any case, it is necessary to understand that the living water in an aquarium is the result of the interaction of many living beings, therefore, time and certain conditions are necessary to restore balance. 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 to replace too often or replace large amounts 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 the launch of the aquarium water can not be changed for 2-3 months, until equilibrium 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.

The water in the aquarium dimmed - what to do?

Muddy water in an aquarium is not only an unpleasant sight, but also a dangerous phenomenon for its inhabitants. In some cases, the turbidity of the water indicates a violation of the ecosystem in the home pond. And this situation requires immediate intervention and elimination of adverse factors that led to it.

Causes of aquarium water turbidity

There are two main reasons why the water in the aquarium dimmed:

  1. From the bottom of the aquarium were raised the smallest particles of soil.
  2. Disrupted biological balance in an aquarium.

The second reason is the most dangerous because it means the presence of bacteria and other organic matter that multiplies rapidly. Particular attention should be paid to the situation when the turbidity occurred not after the launch of new fish and topping up new water, but, as they say, for no reason. But let's talk about everything in order.

Why did the water become cloudy after cleaning the aquarium?

Cleaning the aquarium leads to raising of the particles of fodder and fish waste that have settled on the ground, and also involves scraping off the deposits from the walls of the aquarium. Naturally, after this water turns into a suspension with all these smallest particles.

Many inexperienced aquarists panic at once and do not know what to do if the water in the aquarium dims. In fact, you do not need to do anything. A filter installed in the aquarium will partially remove the solid particles floating in the water. The rest will again settle to the bottom, and gradually the water will again become transparent. As a rule, you just need to wait 2-3 days.

What if the water in the aquarium dims after running the fish?

Natural turbidity is also caused by the launch of new fish. Since with them you start a part of the liquid, which has its own biological composition, you can observe that the water in the aquarium has become turbid. Patience will have to be reserved, because it will take some time until the biological balance is established in the aquarium.

And in order that this balance is established as soon as possible, it is not necessary to immediately rush to change the water. Frequent change of water only delays the process of establishing balance, since everything starts from the beginning.

Microorganisms that have entered the water must undergo a process of competition; this usually takes 2-3 days. No measures need to be taken, all the “extra” microorganisms self-destruct or will be destroyed by beneficial bacteria, and the water will again become clear.

Why the water in the aquarium dimmed and what to do?

When the water grows cloudy without your intervention, that is, not after cleaning or launching new fish, this indicates violations of the aquarium content. You can determine the cause of the color of turbidity:

  • greenish cloudiness suggests unicellular algae breeding;
  • brown tint occurs due to tannins and humic substances present in poorly prepared soil and snags;
  • whitish dregs speaks of the proliferation of bacteria due to the increased content of nitrates.

And in these situations, an immediate total cleaning of the aquarium with full water replacement and thorough cleaning of the filters is required.

Why does the water in the aquarium smell like a swamp?

With the help of an aquarium your home will be filled with beauty, comfort and warmth of exotic reservoirs. 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 its immediate elimination.

If the water in the aquarium began to spawn - the reasons

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, due to which the water is not saturated with sufficient 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 sludge in the soil and water.


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

If the aquarium fluid has become rotten, which has strongly started to smell, and even smells like a swamp, it is possible to establish the causes of the imbalance of the aquatic environment through practice and observation. In the course of the research, it will be possible to determine the method by which turbid water, which goes dead 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 turbid 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. After a few days, smell the tank - if 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.

  3. 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 places, the inhabitants of the reservoir excrete feces with a characteristic aroma. After a day or two, muddy water will appear with a stench. What to do - get a spacious tank, pour water into it with suitable parameters, and populate compatible pets there. 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.


  4. Wrong decorations can "decorate" the aquarium with an unpleasant smell. This is not a perfume, but a living growth, it has its own life. In this case, contact a specialist (a seller in a store or a botanist), and ask whether the purchased plant is able to secrete 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.
  5. When the fish behave excessively actively, they try to lie to the bottom - the reason for the incorrect supply of oxygen, impaired work of aeration. To fix the equipment, you must:
  • install a compressor with high power;
  • replace the filter with a new one, with a forced circulation system;
  • Ask a specialist how to adjust the oxygen supply to 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 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 appropriate 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 the 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 the 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 teaspoon per 20 liters) or scalding them with boiling water. If plaque forms on them, scrape it 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 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 consider compatibility with each other, then your aquarium will resemble a natural biotope, with crystal clear water and beautiful living creatures.
