The fishy smell in the fish tank is terrible, what are the tips to get rid of the fishy smell, easy

Because the fishy smell of the fish tank at home is relatively strong, I have always wanted to solve it, but after a variety of attempts, the problem has been solved recently, and the fishy smell has disappeared. In fact, it is normal for the fish tank water to have a slight fishy smell, but if the smell is strong, it is not normal. I first observed the fish, they were very lively, and they were not sick, and then I looked for food residues in the fish tank, and the water was relatively turbid, so I used the method of changing the water, and the effect after the water change was not obvious, so I thought that there was a problem with the filtration and culture of the bottom filter.

The bottom filter is a standard four-grid, in the first grid I put white cotton and black cotton, in the second grid is a ceramic ring and part of the bacteria house, in the third grid are all bacteria houseThe last compartment is the water pump, and there is no filter material. After opening the bottom filter, the fishy smell is even stronger。At this time, I saw that the first white cotton had become dirty and black due to long-term use, which made me even more sure that there was a problem with my filtration system.

Because the service life of white cotton is about 3 months or half a year at most, but my white cotton has been almost 1 year since the cylinder was opened, and there will definitely be no problems with the filtration effect; There is also the combination of ceramic ring and bacteria house, whether the effect of cultivating nitrifying bacteria is correct or notWouldn't it be useful if we used filter media with better culture effect?

After I re-bought white cotton and bacteria house from the Internet, I also bought rattan cotton and even all-calcium and magnesium filter media, and in the next few days, I replaced all these filter materials in the bottom filter tank in turn, and changed one-fifth of the water every day, through the observation of these daysI noticed that the water became clearer and the fishy smell lessened, not as bad as it was at the beginning

Slowly, people's living standards continue to rise, and the number of people who raise fish at home is also increasing. Farming requires certain skills, such as maintaining good water quality, so that the fish can be raised well. So, many fish friends ask, what if the smell and turbid water quality?

How do I remove it completely? There are three reasons why fish tank water may taste bad.

First of all, the filtration system of the fish tank is not perfect. Secondly, the breeding density is too high and the filtration system is overloaded. The third is that the water is too fertile, and if it remains unchanged for a long time, the water quality will stink.

Removal methods include: If your tank is not well filtered and nitrified properly, it will lead to a large accumulation of ammonia in the tank (released from fish feces or food scraps). If there is an unpleasant smell, it means that it is very serious and may cause your fish to die.

In view of this situation, the water used for aquaculture must be filtered and the nitrification system must be improved. Cultivation is suitable for powerful filtration systems such as bottom filtration and trickle filtration, with sufficient filter cotton and glass rings.

Activated carbon is added to the filter material, and the packaged activated carbon for the aquarium is better. Before entering the fish tank for filtration, clean the lower pool and filter it. It needs to be withdrawn or replaced within a few months.

Activated charcoal has the effect of deodorizing and absorbing pigments. Pay attention to the feeding density. Although there are many types of fish, it also depends on the size of the tank.

If too much fish causes an odor, it is necessary to reduce the density and change the water frequently to improve it. This means changing the water every 3-7 days, changing 1 4-2 5. When changing the water, it is necessary to change the adjusted water temperature and the temperature of the fish tank, the temperature difference should not exceed 3 degrees, and it is best to dry the tap water.

Reduce the amount of feeding, the standard is 2 times a day and eat in 5 minutes each time, you can reduce the feeding once a day and eat in 2 minutes each time. If it is found that there are obvious lesions on the body surface of the fish, it is necessary to consult the fish disease in detail, prescribe the right medicine, and remove the odor in time. Clean the fish tank filtration system.

Wash half of the first half and the other half after half a week to avoid the breakdown of the nitrifying bacterial flora. If you raise fish first, then you don't need to study the water used to enhance the taste of the fish, which is equivalent to understanding how to raise fish in it. Only by maintaining the water quality and giving the fish a good living environment can your fish live a healthier life.

It's really like that, you can smell it every day when you walk by.

The best thing to do is to change the water in the fish tank often, so that it will be a little better.

The fishy smell in the fish tank can choose to change the water frequently, or change the taste of the air with an air freshener.

I think the most effective thing is to change the water and add the oxygen machine frequently.

Use activated charcoal suitable for fish, and change the water frequently.

You need to change the water in the fish tank frequently, and you need to put some plants and other things to get fishy.

That is to change the water in the fish tank frequently, so that there is no smell.

The fish tank should be changed and cleaned frequently, and some products should be bought to remove fishy odors.

The fishy smell in the fish tank is very bad, teach you a few simple tricks, and the fishy smell is easy to have.

Fish tank odor removal tips need to wipe the glass clean, you can use dish soap to clean the glass thoroughly. Then use some cleaning materials, and also need to trim all the dead leaves in the tank, also clean the rocks and decorations inside, and completely remove the water inside, then replace it with clean water, and also clean the filter.

The fishy smell of the fish tank is mostly caused by incomplete cleaning. It needs to be disinfected with potassium permanganate, and it can be changed with clean water.

If there are dead fish and dead aquatic plants, etc., and fail to fish out in time, a large number of bacteria will breed and cause the water to smell. It should be fished out in time. If the fish excrement is too much, the filtration system is not enough nitrifying bacteria to break it down in time.

Wash or replace some filter media, such as white cotton. Activated carbon absorbs odors and impurities. Or use a siphon to clean up the sand bottom, both excrement and garbage.

Temporarily change the water frequently (change 1 4 - 1 5 tanks of water every day), buy nitrifying bacteria every day to speed up the establishment of the nitrification system. Note that the difference in water temperature should not exceed 2 degrees, if you have not been exposed to the water, buy some fish for use. When nitrifying bacteria are not well established, change the water frequently, and change 1/3 of the water every three days.

Fish farming starts with water, and only good water quality is suitable for the growth of fish. Novice fish farmers, do not rush to buy fish after purchasing a fish tank, you need to leave the tap water for 7 to 10 days, during which time you will inject some fish maintenance drugs into the fish tank, and then buy fingerlings for stocking.

Here's how to get rid of the fishy smell in the fish tank:

1. Add high-quality nitrifying bacteria capsules or water agents to the filter tank, and the filtration system and oxygenation equipment are open 24 hours a day.

2. Don't feed too much.

3. If there are dead fish, clean up the dead fish carcass in time.

4. Clean the bottom sand regularly, the bottom sand is easy to leave food and fish feces.

Reasons for the fishy smell in the fish tank:

1. There are dead fish, stagnant water weeds, etc., which cannot be fished out in time, breeding a large number of bacteria and causing the water to smell.

2. There is too much fish excrement, and the filtration system fails to decompose in time.

3. If there is bottom sand, fish manure and leftover feed may sink to the bottom of the sand.

If you want to get rid of the fishy smell in the fish tank, you need to find the fishy smell first. If it is caused by the deterioration of the water quality, it is necessary to change the water regularly so that the water quality can be improved. If it is caused by overfeeding, it is necessary to control the amount of food or remove the bait residue when changing the water.

If it is caused by dead fish, it needs to be taken out as soon as possible. If it is caused by anaerobic bacteria, it needs to be oxygenated in the fish tank. <

1. Poor water quality: If the water is not changed for a long time, the water quality will deteriorate, which will make the fish tank smelly. The best thing to do in this case is to change the water regularly.

Usually it should be changed once a week, but if the water quality is maintained, it can also be changed once every two weeks, and a fifth of each change is enough.

2. Dead fish rot: fish farming will inevitably encounter some problems, such as water fluctuations, water temperature changes, etc., which may make the fish die, once the dead fish rot, the fishy smell in the tank will also be aggravated, this time the dead fish need to be fished out in time, so as not to pollute the water quality.

3. Fish body injury: fish may scratch some things in the tank, resulting in body surface injury, and the wound will be infected by bacteria and become inflamed and rotten, which will also make the water body smelly, so we must pay attention to not put some sharp things in the tank and isolate it after injury.

The main thing to get rid of the fishy smell is to change the water diligently, and other methods are not curable.

Cutting a few slices of ginger or garlic can relieve the fishy smell of the fish tank and also prevent enteritis in the fish.

The best way to remove the smell is ginger, which can be added a little more to remove the fishy smell.

The fish tank must be washed frequently and the water must be changed more often to keep the fish tank clean.

If you change the water in the fish tank for more than a week, you can reduce the fishy smell.

Change the water in the fish tank frequently to keep the bathtub clean and hygienic.

That is, the water has been left for too long, and it can be improved by changing the water.

To some cooking wine, come to the onion and garlic and simmer over high heat, but not dry the pot.

It makes sense, ginger cooking wine with a little pepper has a good effect on fishiness.

I would suggest that it would be much better to change the water more often.

You can pour out the water and fish and wash them with vinegar and a rag.

Ginger is OK, and cooking wine can also be used to remove the smell.

I think that the fishy smell in the tank is actually the change of water quality, from good to bad change, at this time we must pay attention to changing the water, if you don't get it right, you may have to die fish, personal experience if the fish is not wrong, the water will not be fishy!

If you are lazy, don't raise fish, both people and fish will suffer.

What is the use of removing fishy odors? Treat the symptoms but not the root cause.

There are many reasons why the fish tank is fishy, such as the filtration system is not very good, or the water has not been changed for a long time, and the fish is sick and the fish smell is also caused by the fish tank.

1. Imperfect filtration and nitrification system in the fish tank will lead to the release of ammonia from fish excrement or food residues, which is very likely to lead to the death of fish. In view of this phenomenon, it is necessary to strengthen filtration, improve the nitrification system, and place enough filter cotton and glass rings;

2. Add activated carbon to the filter material, and it is better to pack a package of activated carbon for aquarium, clean the lower tank and filter it in advance and then enter the fish tank for filtration. After a few months, it will need to be withdrawn or replaced with a new one. Activated carbon has the effect of deodorizing and adsorbing pigments;

3. If there are too many fish that cause a strong fishy smell, then reduce the density, and then change the water frequently to improve.

4. Reduce the amount of feeding, the standard is to eat 2 times a day, 5 minutes each time, 5. If you can find obvious lesions on the surface of the fish, prescribe the right medicine, and remove the odor in time;

6. The addition of nitrifying bacteria may also be slightly improved;

7. Clean the filter system of the fish tank, wash one half of it first, and then clean the other half after a week to avoid the collapse of nitrifying bacterial flora.

It turns out that it is so simple to remove the fishy smell, and most people don't know it, so it's a good way to collect it quickly.

To remove the fishy smell of the fish tank, it is best to clean it with bleaching powder.

Placing the following items can help remove the fishy smell from the fish tank and do not harm the fish:

1. Place bacillus in the fish tank. Bacillus subtilis and Bacillus licheniformis can be used as livestock and aquatic feed additives, and Bacillus can directly decompose hydrogen sulfide in the water body for water purification, so that your fish tank taste can be reduced, and it can generally be bought in feed stores.

2. Place photosynthetic bacteria in the fish tank. After photosynthetic bacteria are applied to the water body, it can degrade the residual feed, fish feces and other organic matter in the water body. At the same time, it can also absorb and utilize harmful substances such as ammonia, nitrite, hydrogen sulfide and other harmful substances in the water body.

The application of photosynthetic bacteria can effectively avoid the accumulation of solid organic matter and harmful substances, and play a role in purifying water quality and removing fishy odor.

3. Place activated carbon in the fish tank. As an environmentally friendly adsorbent, activated carbon has the advantages of strong adsorption and catalytic properties, sufficient raw materials and high safety, acid and alkali resistance, heat resistance, insoluble water and organic solvents, and easy regeneration.

Activated carbon has an obvious clarifying effect on turbid water quality, can remove odor and odor in water, and also has an excellent filtering effect on bacteria. Activated carbon is the most common in life, and it can be bought in general supermarkets and agricultural machinery supply stores.

1.Use activated charcoal suitable for fish.

2.Change the water frequently, once a week in winter.

3.A little salt in the water is the most trouble-free way, and it can also prevent the ** disease of the fish.

The fish tank has a fishy smell, and the best way to deal with it is to change the water. Changing the water is an essential step in the process of fish farming, it can improve the water quality, reduce the content of harmful substances in the water, and also has a good effect on removing fishy odors. It should be noted that the water should not be changed too frequently, otherwise it will pose a certain threat to the health of the fish.

2. Strengthen filtration.

The reason for the fishy smell is that the water has a relatively high content of ammonia nitrogen, and the best way to remove ammonia nitrogen is biological filtration, that is, to cultivate nitrifying bacteria. Nitrifying bacteria can convert ammonia nitrogen into nitrate, thus avoiding poisoning to fish. It should be noted that the filter media should not be cleaned frequently, otherwise the nitrification system will be damaged.

3. Reduce feeding.

The high content of ammonia nitrogen in the water is due to the decomposition of organic matter, and the ** of organic matter is fish food. Usually feeding must control the amount of food, not too much, each feeding should be eaten in about 3-5 minutes. Also, if there is too much bait residue in the water, it is best to clean it up and suck it up when you change the water.

Fourth, remove dead fish.

If a fish dies in the tank, it will also produce a fishy smell. In this case, it is necessary to remove the dead fish in time and disinfect it properly to prevent other fish from dying.

The second possibility is the largest, add activated carbon to the filter material, and it is better to pack the special activated carbon for the aquarium, clean the lower tank in advance and filter it before entering the fish tank for filtration. After a few months, it will need to be withdrawn or replaced with a new one. Activated carbon has the effect of deodorizing and adsorbing pigments;
