The Water In The Aquarium Smells What To Do

Getting rid of

Each owner of an artificial reservoir, as soon as he noticed that the water in the aquarium with fish begins to grow cloudy, tries to decide for himself what to do and how to deal with this phenomenon. Considering all the causes of mechanical turbidity of water, it is necessary to apply the following methods to eliminate this phenomenon.

Do a good cleaning in the pond:

  • Carry out a water change;
  • Siphon the bottom;
  • Clear all surfaces.
  • Clean and wash the filter;
  • Install an additional new one or replace both filters with one powerful element.

Turbidity of water and a green tint of mechanical origin will help to remove the filler from the padding polyester, it is placed in a filter instead of a regular sponge. Explicit changes will be visible after 24 hours.

Another method of removing cloudiness is activated carbon. This absorbent removes impurities in the pond. The charcoal is put into a filter and left inside for 14 days. Lack of coal is the inability to absorb nitrates and nitrites. The absorbent zeolite will cope with this task. Zeolite is an effective means of dealing with a problem that has arisen. The drug is a group of water aluminosilicates of calcium, sodium and minerals similar in composition and properties.

If the water in the aquarium is contaminated due to biological factors, a number of important steps must be taken to restore the balance:

  • Clean the walls of the vessel;
  • Clean the bottom and substrate;
  • Adjust the amount of feeding;
  • Weekly water change in the amount not exceeding the norm.

For the rapid restoration of standard indicators, specialized drugs should be used to suppress harmful organisms and provoke the development of beneficial bacteria.

Water change

An imbalance in an established reservoir indicates insufficient and improper care of the internal environment. If the liquid has become of poor quality and becomes cloudy after changing the water in the aquarium, the reason may be inaccurate filling, as a result of which all suspended particles from the substrate rose up. It is forbidden to change the liquid by more than 1/3 part more than once a week. After such a change in the environment in a long-neglected reservoir, the biological balance will be disturbed.

Water color. finding the problem in the aquarium

It is not uncommon for cloudy water in an aquarium to take on color. The shade of the liquid can be different, each color indicates a specific problem inside the reservoir. Shade options:

  • Green;
  • Grey;
  • White;
  • Brown;
  • Unusual color.

The green color of the reservoir indicates the reproduction of algae, microscopic in nature. Turbid green water in an aquarium can occur for several reasons, namely:

  • Excessive direct sunlight of natural or artificial origin;
  • Poor filtration;
  • Poor quality water.

If, after changing the place of the reservoir to a darker room, the green tint has not changed, you should look for the cause in the filter system. It is recommended to install a quality filter to reduce the amount of phosphates and nitrates. Water should be sent for analysis, if the above elements exceed the norms, such a liquid must be replaced with the safest one. If the analysis does not show supersaturation with these substances, it is recommended to reduce the fish feed with dry mixtures. For effective control of microscopic algae, daphnia feeding on them can be placed in the vessel.

The Water In The Aquarium Smells What To Do

If the water in the aquarium has become cloudy and has acquired a brown tint, you should look for the cause in wooden decorations. Elements from wood emit humus and tannin into the surrounding aquatic environment, as a result of which the liquid is colored. There is no critical danger for the inhabitants of the reservoir, however, the acidity level may slightly change. To prevent staining, it is recommended to soak all new wooden elements. The water can turn tea-colored due to the presence of peat extract during filtration.

The appearance of unicellular algae and their excessive reproduction leads to the acquisition of white water. There are several reasons why algae appeared and the water turned white:

  • Newly launched vessel with new water;
  • There was a water change over the norm;
  • Overpopulation of the vessel with living organisms.

It happens that the water becomes whitish and cloudy after the treatment of fish. Drugs for treatment have side effects, among which is a violation of the internal biological balance. The appearance of white turbidity is the struggle of the internal biological environment with accumulated poisons in the aquarium.

If the water in the aquarium becomes cloudy and gray, the problem is usually a contamination of the substrate or the presence of silicates, heavy metals and phosphates in the environment. To determine the presence of harmful substances in the aquatic environment, a special indicator or litmus paper is used, which are used to confirm the level of alkali.

Other reasons

If after cleaning the aquarium the water becomes cloudy again, the reasons may be as follows:

  • Low-quality decor elements;
  • Poor and irregular care.

All of the above factors, as a result of which the water in the aquarium is cloudy even after replacement, are mechanical reasons and can be easily eliminated.


Often, the water becomes cloudy in a new aquarium, since after starting up, a lot of bacteria multiply in the reservoir. This process is natural and inevitable. It is recommended that after starting a new aquarium, start fish no earlier than on the second day. If it is noticed that the water becomes cloudy, you should wait until the reservoir clears itself, and then start the fish. In the absence of nutrition, bacteria will die, the water balance will be restored.


To restore the biobalance and combat turbidity of a biological nature, the following measures are used:

  • Siphoning the substrate;
  • Frequent water changes;
  • Increased aeration;
  • Adding quality water.

These measures will reduce the amount of organic material and free-floating heterotrophs in the aquarium water. However, just filtering the aquarium water and adding a new portion of the water when changing is not enough. For preventive purposes, chemicals are used.

Filter or number of fish

If a large number of fish live in the reservoir and the aquarium filter is working poorly, this can cause cloudy water. In fish, such water causes intoxication with decay products, leading to death. Overpopulation with fish is unacceptable, the amount must strictly correspond to the volume of the aquarium. For each living organism, it is necessary to calculate the standard volume of water; on average, 2 liters of water should fall on 1 cm of the fish body. It is recommended to leave a margin, taking into account the growth of pets. Even the highest quality filtration system cannot cope with the problem of consumption of waste products.

Often the reason why water deteriorates is a failed filter. It can become clogged, ceasing to remove the necessary debris. Such a device must be thoroughly cleaned and it is advisable to change the layer to improve filtering. The cloudy liquid will recover in a few days.

Why arises

Cloudy aquarium water is a challenge faced by many aquarists, regardless of experience. This problem often leads to the death of fish. To prevent death, it is important to understand the causes of cloudy water in the aquarium.


The water will become cloudy after the first start-up of the aquarium, if unprepared soil is placed on the bottom of the container so that the water does not become dirty, it is important to rinse the substrate well to remove small particles and dust. It is necessary to rinse until the water during rinsing becomes clear and clean.

Water quickly becomes cloudy when the feed decays. Overfeeding fish leads to an increase in the amount of uneaten food residues, the particles sink to the bottom, where they begin to rot. Living in such an environment is dangerous for their life and health. It is recommended to feed the fish so that all food is eaten in 15 minutes.

The water in the aquarium stinks what to do. Aquarium water smells

A beautiful and harmoniously located aquarium in the room can be a decoration for any interior. The aquarium is a great way to relax and achieve inner balance. However, both the fish themselves and their home need constant and competent care. Beginners and even experienced aquarists often face unwanted and unpleasant situations that are the result of improper or inadequate care. One of these situations is when the water in the aquarium smells unpleasant.

Let’s try to find out why the aquarium water smells and what actions can be taken to eliminate unwanted odors from the aquarium.

Why does the water quickly become cloudy in fish?

Clouding aquarium water: action

If frequent water changes, the growth of bacteria and algae have provoked the appearance of cloudy water in the aquarium, you need to take some steps to eliminate the problem.

  • If your tank is overcrowded, place your fish in separate tanks where they are comfortable and spacious.
  • If there is too much light, shade the aquarium by placing it in a secluded area out of strong light.
  • If the water becomes cloudy the day after the first feed, siphon the bottom and feed the fish in small portions.
  • Place snails and fish in the aquarium, which eat food debris from the bottom, clean the glass and water of the tank. After a few days, the water will be free from dirt, and does not require an additional change.

Causes of cloudy aquarium water

Why did the aquarium water quickly become cloudy if the tank is equipped with a filter? The main problem is that on the very first day of launching the aquarium, there is no integral and constant biological environment in it. The so-called “bacterial explosion” is caused by the active growth of the number of unicellular microorganisms that are constantly multiplying. In this case, the fish should not be populated, it is better to do it on another day. When the microflora in the container is balanced, then the water will become crystal clear. You don’t need to do anything serious. this sediment will pass by itself. If you decide to change the water, it will again become cloudy and unsuitable for life.

For 4-7 days, the aquatic environment will fully recover, plants and fish can be launched into it. To speed up the process, you can add water after the old aquarium with “living” water.

Another common problem with rapid cloudiness in an aquarium is poor water filtration. The cleansing system should be well thought out, and this should be done quickly, while the fish are young and have not had time to get used to the new home. A bad filter does not allow grains of dirt, feces, food debris to pass through, provoking the formation of decay products. Such rotten water constantly stinks and can cause disease.

Take a look at filtering water in an aquarium.

Why else does the water quickly become cloudy? If it becomes an unpleasant green color, becomes cloudy in a short time, it means that microscopic blue-green algae develop in it, which lead to the bloom of the reservoir. With good organic development and strong lighting, they make themselves felt on the fifth day. When there is not enough light, cyanobacteria will turn brown and start to rot. Green color of liquid with turbidity, unpleasant odor. signs of growth of blue-green algae.

Causes of aquarium odor

Perhaps every lover of aquarium fish has come across a situation when the water smells unpleasant or even stinks. The reasons for this phenomenon can be different:

So, in most cases, the unpleasant smell of water is a consequence of the excessive activity of putrefactive bacteria or plant organisms. Therefore, the main task of the aquarist is not to allow microorganisms to multiply too intensively and plants to bloom too abundantly.

How to eliminate bad odor in your aquarium

Let’s say you figured out why the water in the aquarium smells. What measures must be taken to eliminate this problem?

The first thing to do is to thoroughly clean the aquarium with all its contents. General cleaning is carried out according to certain rules. It is necessary to consistently clean the walls, bottom, stones, algae and all other elements of the dwelling for fish. Rotten algae and excess plants should be removed.

Changing the water in the aquarium is carried out gradually. it can take 5-7 days. A complete and simultaneous water change is carried out in exceptional cases: this is a huge stress for fish, which can lead to the death of fry and especially sensitive species.

Other methods of combating unpleasant odors are saturating the water with sufficient oxygen, changing feed or regulating its amount, ensuring the optimal amount of light radiation. If the aquarium is overcrowded, some of the inhabitants should be transplanted into another container, sold or donated: it is better to lose some of the pets than to constantly face the problem of an abundance of feces and harmful bacteria. In an overcrowded aquarium, fish feel uneasy and often show aggression towards each other.

Why on the second day after the establishment of the aquarium the water smelled

You have not provided any information on the aquarium. This usually happens with large leftovers of food and dense planting of fish, especially scrofula, we like to plant 10 pieces per liter, and they shit like elephants.

Either the water was initially unusable, or you started the fish too early, food decomposing in the water may be to blame. The case can also be in uncleaned soil. And in general there may be more reasons, but I have indicated the main ones to you.

The aquarium is 60 liters, and only 9 fish were launched there: three gupias, three neons and three zebrafish, all. I don’t know what to do now.

The aquarium is 60 liters, and only 9 fish were launched there: three gupias, three neons and three zebrafish, all. I don’t know what to do now.

With a high degree of probability, early planting fish in a recently flooded aquarium, you did not allow the so-called biological balance to be established. As perchikbest told you, most likely the water has deteriorated because of the food, which, when decomposed, leads to a sharp increase in the number of bacteria in the water, because of which it actually stinks. If the aquarium is properly started at the stage of settling the water in the aquarium for 7-14 days (experienced aquarists can prepare the water in less time), a slight odor and turbidity of the water is acceptable, but then the ciliates do their job by destroying bacteria, the water becomes clear and odorless, and then you can start the fish. But even in a long-established aquarium, overfeeding can cause spoiled water. In your case, it is best to restart the aquarium by changing all the water and letting it settle normally. For 3-4 days you can plant a little grass, this will help to quickly establish a microclimate favorable for fish. And after 5-7 days (to be sure), you can launch fish. But for the future. Be careful with feeding

There are also special means for restoring and purifying water from cloudiness, but I cannot say which ones are better to use, I did not have to resort to them. And in general I am an opponent of such chemistry. But if there is nowhere to plant the fish, then you can try this option.

The aquarium is 60 liters, and only 9 fish were launched there: three gupias, three neons and three zebrafish, all. I don’t know what to do now.

It is optimal to get hold of friends-acquaintances with water from a safe (preferably herbalist) aquarium, rewash the aquarium and soil, etc. And start the aquarium on the aquarium water. Everything about everything will take 2 hours maximum. This is almost guaranteed to keep the fish alive. During washing, put the fish in aquarium water in any suitable container and supply air.
After starting the fish, do not feed at all for 5 days. There will probably not be enough water, so add about 10-20 percent daily and so on until the full volume. The main thing is not to feed the fish. And remember. a healthy fish is a hungry fish (within reason).
Feed the fish just a little so that they eat everything in a couple of minutes. For your fish, it is better to give in parts, because Fish almost never take from the bottom.
If there are plastic grottoes, driftwood, etc., then it is better to replace it with natural ones, because they can release all kinds of crap into the water, from which it can also smell. Well, preferably plants. If there is not enough light, then Anubais will help you.
Something like this.

Now urgently clean the pump. A filter with a soil siphon cleaning with a drain of 10% water. The smell comes only from excess feed. If all the fish are alive. Do not feed the fish for 4-5 days and the water should = come out =.

Maybe go zabagato

In my opinion, you don’t need to take a steam bath. A little “fish” the aquarium water always smells. It is unlikely that you threw tons of food for such an amount of fish, it is unlikely that the water is disgustingly three meters high. Give the system time to settle and balance, and everything will work out. Well, do not feed for several days. That’s all.

Here the fact is that sometimes a smell appears in the aquarium that is completely unimaginable and absolutely intolerable. For 45 years in the aquarium hobby, I could not even imagine that I would face such a disaster. And I had to enjoy it to the fullest three years ago. I have a 35-liter aquarium in which I kept a savage apistogram. The aquarium is fully equipped with good vegetation. The purpose of this aquarium was as follows: to get offspring from the brought fish as soon as possible. And the fish brought from the river, as a rule, start to get sick from time to time. And as a consequence of the outbreaks of the disease, I sometimes performed the treatment of fish right in that aquarium. With all my medicines, I knocked the balance completely off. Rather, the fish lived and spawned, but a marvelous in its strength and very unpleasant stench came from the aquarium. It was not the stench of rotting organic matter, and not the stench of fish, but some kind of chemical, unlike anything that I smelled before. over, the level of stench was such that even a crack in the cover glass for inserting the compressor tube filled the whole room with the unforgettable aroma of chemical production.
And how I just did not fight with her. I changed the water daily in the amount of 90%, pouring it from a healthy aquarium instead, removed all the plants, siphoned the soil. Nothing worked. After changing the water, the stench dulled for a day, but then returned again. It all ended with the fact that I completely restarted the aquarium, calcining the soil in the oven. He poured water from the tap. Everything was calm for a week, but then a relapse began. I had to restart everything again, install UV, and only after that everything ended happily.

Unsuitable plants

Unusual plants decorate the aquarium, but the selection of aquatic flora requires special knowledge. Incorrect planting can lead to an unpleasant odor in the following cases:

  • Little space: you need to extract some of the plants.
  • Natural specific smell of vegetation: such algae are completely removed.
  • Lack of plants with a large number of putrefactive microorganisms: it is necessary to plant new vegetation and ensure high-quality filtration.

Why does the water in the aquarium stink and how to deal with it, will tell you:

Untimely cleaning

An important aspect of aquarium maintenance is regular and delicate cleaning. If not cleaned in time, the plants become covered with mucus, plaque appears on the walls of the aquarium, the water becomes cloudy and fetid.

It is necessary to strive for such a ratio of water, plants and animals in which the aquarium ecosystem copes with cleansing on its own.

Intervention in the life of a properly organized aquarium in the form of a complete cleaning can be minimal, up to 1 time per year. In the intervals between general cleanings, it is enough to monitor the operation of the filters and process the soil with a siphon.

In the case of a neglected aquarium, you cannot do without global cleaning. It includes:

  • Washing of soil and decorations;
  • Cleaning the walls of the aquarium;
  • Removal of overgrown plants;
  • Filter cleaning.

To maintain cleanliness, it is important to regularly refresh the water by scooping up a quarter and adding as much clean and settled water. You can also add cleaner fish and snails to the aquarium.

Consequences for fish

When the equilibrium of the ecosystem is disturbed, the environment changes for the worse. The water becomes cloudy, and a subtle smell can turn into an intolerable stench.

Such changes entail adverse consequences for the inhabitants of the aquarium:

  • Loss of appetite in fish;
  • Decreased vitality of pets;
  • Damage to plants;
  • The emergence and spread of infectious diseases;
  • Changes in the bacterial composition of water;
  • The death of fish and other animals.

Silt appearance

Soil siltation (detritus formation) cannot be considered a negative factor: it contributes to the biological health of the entire aquarium.

The flip side of the coin is that excess silt leads to disruption of aeration processes in the soil:

  • Oxygen decreases;
  • The bacteria die;
  • Toxins and poisons remain in the aquarium.

The algorithm of the aquarium owner’s actions depends on the state of the bottom filler:

  • If the soil is completely covered with detritus, it is necessary to clean it with a siphon over the entire surface, except for planting sites. Silt is a substrate for their growth and development.
  • In case of excessive silt after cleaning with a siphon, change the water by a quarter. You can continue the change once a week for 1-2 months, focusing on the condition of the soil and water.
  • In neglected and unkempt aquariums, a complete replacement of soil and water is permissible.

Large amount of soil

The soil plays an important role in the life of the inhabitants of the aquarium. Besides creating beautiful decorations, it copes with the functions:

  • Substrate for aquatic plants;
  • Creation of suitable conditions for the development of microflora in the aquarium;
  • Water purification.

However, in excess, it tends to acidify due to increased bacterial growth.

Reducing the volume of soil is a logical solution to the problem, but first you need to determine:

  • Water condition. It may need to be refreshed or replaced.
  • The optimum ground height, which depends on:
  • Type of filler;
  • Aquarium size;
  • The number of fish and plants.

The soil, selected correctly and in the right amount, will not sour and spoil the water in the aquarium.


The following guidelines will help you understand when fish and other pets need help:

  • You need to monitor the inhabitants of the aquarium. Unusual behavior, loss of appetite, excessive sluggishness are warning signs.
  • Use high-quality filters in which the water flow rate can be adjusted. Check the condition of the sponge inside the filter.
  • Aeration must be optimally adjusted.
  • Buying soil, plants, fish and other inhabitants requires some knowledge. You cannot fill the aquarium at random.
  • So that the water does not turn out again. adhere to the recommendations regarding feeding and cleaning.


An undersized tank in relation to the number of fish increases the risk of bad odor.

The problem can be solved only by increasing the living space:

  • Transfer some of the fish to another container.
  • Get a larger aquarium.

The final decision making depends on additional factors, which include:

  • The total number and size of living creatures: on average, each fish needs 1 liter of water for every centimeter of body;
  • The presence of plants and decorations in the aquarium that take up part of the space;
  • Having a suitable place in the house for one large or second small aquarium.

In the future, it is necessary to continue to control the number of fish and to resettle them in a timely manner, if necessary.

Causes of a fetid odor and how to eliminate it

The following factors can be the root cause of imbalance and the appearance of a bad smell:

  • Incorrect operation of additional devices, accessories for the aquarium (filter, aerator);
  • Improper care (overfeeding, rare cleaning, excess soil, unsuitable plants, silting);
  • Natural consequences of life (excessive reproduction of fish and microbes, the death of one of the inhabitants of the aquarium).

Why is the aquarium cloudy: causes and remedies

Owners of domestic fish, who are simply lovers of the underwater world or professional aquarists, may occasionally encounter the problem of cloudy water in an “artificial reservoir”. Why does the water in the aquarium become cloudy? How to deal with turbidity and how to avoid a similar problem?

  • Cloudy water in the aquarium: the main causes of the problem

Cloudy water in the aquarium: the main causes of the problem

Even a beginner in the aquarium hobby, when asked about water turbidity, will say that this problem arises from pollution in the “artificial reservoir”. And he will be right. However, there may be several reasons for the appearance of turbidity in the reservoir, regardless of its size. And among them, one can single out key reasons, most of which require some measures.

Why does the water in the aquarium become cloudy? Main reasons

  • The presence in the “home reservoir” of small particles of soil, pollution that are in suspension, thereby creating a muddy drag. A similar reason may arise due to improper soil cleaning, when new water is poured into the tank and if there are fish in the aquarium that live at the bottom and often break the existing sand. This foundation is harmless enough.
  • Excess feed. It can both float inside the tank and sink to the very bottom. If the inhabitants of the “artificial reservoir” do not absorb the food that has settled down, it begins to rot, releasing phosphates. Hence the following reason for the appearance of turbidity.
  • Reproduction of bacteria inside the aquarium. They feed on food and waste products of aquatic inhabitants not eaten by fish. In some cases, when the colonies of bacteria of different types become excessively large, this reason for the turbidity of the water becomes negative, which must be dealt with. The same reason becomes the answer to the question of why the water has become cloudy and smells.
  • Changes in the transparency of water due to nitrites and nitrates, which are the result of the life of aquatic inhabitants. When the aquarium is not cleaned properly or there are no special filters in the tank, this can also lead to cloudy water.
  • Over-saturation of the “home reservoir” with fish and other underwater inhabitants. If there are ten fish in a small aquarium, an abundance of greenery and decorations, then this will lead to the formation of a cloudy drag. There is a rule: one medium-sized fish should have at least a liter of water.
  • Lack of a purification system, filtration inside a home aquarium.
  • Changing the water in the tank too often and completely. The assumption that seemingly “spoiled” water should be completely replaced immediately, and the aquarium itself and its inanimate contents should be thoroughly washed, is a delusion. Such measures will lead to a violation of the biological balance in the “artificial reservoir” and provoke the growth of bacterial colonies. As a result, the water will become even more cloudy.
  • The appearance of algae in the aquarium. Algae of any order is considered a threat to the “home water”. They grow very quickly, are prone to flowering, which is why the water loses its transparency and changes color. As a result, “black beard” algae, which are parasitic organisms, can appear inside the reservoir and it can be difficult to get rid of them. Therefore, it is better not to bring the aquarium to such a state. In addition to turbidity, algae add an unpleasant odor.
  • A change in the acid-base balance within the reservoir, which occurs both due to the vital activity of bacteria, fish and other aquatic inhabitants, and due to the use of any chemicals that change the composition of the liquid.
  • The water in the aquarium can become cloudy due to an excess of oxygen in it, which can also lead to the death of the fish. In addition, too hard, chlorinated and unsettled water will look contaminated.
  • Bringing new wood ornaments, such as sticks and small driftwood, into the “home pond”, can cause a sudden and sudden cloudiness of the liquid in the tank. This is because the wood in the water releases tannins, tannin, which affect the purity of the contents in the aquarium. The presence of peat, as well as colored new pebbles, can also provoke turbidity.

How to identify the cause yourself and when to purify the water

A number of reasons for the appearance of cloudy water in an aquarium are not difficult to determine. Dealing with more complex causes, based on a bacterial factor or algae, will help change the color of the liquid in the tank.

Four color options for contaminated water

If the question arises why the water darkens, becomes brownish, as shown in the photo below, then the reason often lies in the abundance of wooden elements inside the “home reservoir”.

The greenish tint shown in the following photo signals excessive algae activity. A characteristic wet-putrid smell from the surface of the water surface is added to the flowering.

The presence of a whitish tone indicates an increased activity of bacteria and ciliates, unicellular organisms. This can lead to the extinction of all fish and other inhabitants of the aquarium. And also provoke an unpleasant amber. An example of such turbidity is shown in the photo.

The fourth option can be the color of the water in the same tone with the ground or with numerous small multi-colored pebbles.

In a situation with brown haze, it is enough to get rid of the wooden element. And if the water in the aquarium becomes cloudy due to the soil, you need to wait a while, when its particles settle to the bottom by themselves. Or remove the contents and rinse thoroughly under running water, washing out fine grains of sand.

Additional information and recommendations

During the fight against whitish turbidity, it is worth refraining from replacing water, even in small quantities. The new liquid will provide additional nutrients to the growing bacteria colonies. Therefore, in this way, it will not work to purify muddy water.

When a new tank is started, you should add water from old aquariums to it. It will have a beneficial effect on the microclimate in the “home reservoir”. The resulting cloudiness in this case will disappear after 3-5 weeks. Change the water in a new aquarium only after 3-4 months of use.

Additional recommendations

Proper fish care, including proper water purification, is troublesome and requires a lot of patience. However, following all the recommendations, taking into account the characteristics of the fish, it is so difficult to get rid of the cloudy water in the tank. Thus, you will simplify the process of keeping underwater pets.

Smell in the aquarium: causes

Small inhabitants of reservoirs are characterized by certain aromas. From this it follows that no smell at all can come from them. Accordingly, when approaching the fish, we do not feel a very pleasant smell. This is normal. BUT! If the smell grows, it becomes more terrible, you need to take action.

The first step is to find out why the water in the aquarium stinks. The reasons for the odor are as follows:

  • There is a lot of food residues at the bottom of the aquarium.
  • Large quantities of fish waste products.
  • Insufficient water filtration or incorrect filtration.
  • An unnoticed dead fish rots under algae / stones.
  • The soil sours (hydrogen sulfide is released, which is a mortal danger to the life of fish).
  • Unfair or untimely cleaning of the water world.
  • Insufficient oxygen (water circulation problem). When there is not enough oxygen, the water quickly becomes cloudy.
  • Poor quality flora.
  • Over-saturation of the marine world with fish (little water per adult).
  • Poor quality food, overfeeding of pets (it does not matter if it was a one-off overfeeding or not).
  • Silt formation in water / soil.
  • Clogged filter with feed.

The water in the tank began to turn cloudy and smells like a swamp: causes, prevention.

“Why does the water smell like swamp? The entire underwater world smells like mud! The water is cloudy, what should I do? How do you remove awful scents? ”
The answers are pretty simple, being mindful is the one you’ve already received. Let’s repeat and fix: insufficient oxygen (water circulation problem). When there is not enough oxygen, the water quickly becomes cloudy. Fish burrow under stones, muddy the water. Proceed as follows: readjust the aeration and clean the filter. Also, hydrogen peroxide tends to saturate water with oxygen. It will be useful to purchase a device that measures the pH level of water.

The second answer is also given above: a large amount of peculiar feces excreted by fish from crowding and oversaturation in the tank. From this, the water becomes cloudy very quickly. The fact that the water “smells” is not worth talking about. Set aside the fish, clean out the aquarium. In addition to oversaturation of the aquarium, the reason may be the following: the inhabitants do not match each other in compatibility. Then the same thing happens: copious discharge of disgusting-smelling feces.

When the pH level in the water is insufficient, the soil turns sour, silt appears. As a consequence, the appearance of hydrogen sulfide is inevitable. The presence of this substance in the tank will not bring joy to pets.

In two out of three cases, the water becomes cloudy due to plants. There are two options here:

  • Plants have little room.
  • Plenty of room for plants.

Accordingly, you should offer them a new habitat: a larger or smaller aquarium.

In order to prevent awful odors and cloudy water in advance, you need to do the following: get “orderlies” of the aquarium (snails, speckled catfish, ancistrus and others). They will help keep the reservoir clean, beautiful, healthy.

The water in the aquarium stinks, what to do, how to remove the smell?

So why the aquarium water smells like you’ll have to figure out step by step, going over each of the above reasons. Start by cleaning the aquarium more often. If you are convinced that this was the cause, congratulations! You got off easy, if not, try changing your fish food. Perhaps the reservoir smelled of rotten meat precisely because of the low-grade feed. Remember, in order to give the fish new food in the morning, you need to change the water, clean the tank, clean the filter. Nobody said it was easy!

And it didn’t help? Well, give your pets a fasting day. Overfeeding is a direct consequence of the bad smell from the aquarium. Alternatively, feed the fish smaller, granular food so they can swallow it in one go.

Further. Make sure there is enough room for all the fish in your tank. Move several fish of the same species to another location. It is a known fact: when the fish are cramped, they secrete more feces with a characteristic (disgusting) odor. Consider this.

Why does the water in the aquarium smell and stink?

Why does aquarium water smell? This question is asked by every owner of the aquatic world. Keeping fish is not as easy as it seems at first glance. Fish, like other pets, require attention, time, adherence to certain rules for the care and maintenance.

Often, with proper care, which you cannot imagine better, an unpleasant smell of water in the aquarium still appears. It’s unavoidable. From any pet comes its inherent aroma. The case with fish is special, it is worthwhile to figure it out: water or the reservoir itself “smells”?

The tank itself “smells”, not water: how to get rid of the awful smell.

You have done all the cleaning work in good faith, you have not forgotten anything, you have checked everything, but the unpleasant scent remains. What to do, how to be?!
Check if you have washed the aquarium lid and cover glasses. They have such a feature: to accumulate aromas. Absorb like a sponge. In addition, due to the high humidity inside the lid, colonies of bacteria and algae can germinate. Food may leak between the glasses. Over time, the smell will appear from this. Remains of dry food may accumulate on the lid, which did not get to the fish. You also need to deal with all these factors. Don’t forget about these little things.

Caring for fish is a complex business that requires time, attention, patience, and proper equipment. The life and health of marine life is in your hands. It’s up to you to decide whether the life of the tank will be healthy, blooming and smelling, or dirty, sick and having horrible smells.
