How to deal with the fishy smell in the fish tank, how to solve the fishy smell in the fish tank

The fish tank has a fishy smell and is treated like this:

1. Clean or replace some filter media, such as replacing the filter sponge and activated carbon to absorb odors and impurities.

2. Clean up the bottom of the sand with a siphon, and suck out the fish feces and residual bait in the sand.

3. Change the water frequently, 1 5 cylinders of water are suitable.

4. Add nitrifying bacteria for sterilization.

The reason why the fish tank is watery.

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

2- The excrement of the fish is too much, and the filtration system or nitrifying bacteria are not enough to decompose in time.

3- If there is bottom sand, fish feces and bait may accumulate, and the water will become smelly.

Try the following methods.

1. Clean or replace some filter media, such as replacing the filter sponge and activated carbon to absorb odors and impurities.

2. Clean up the bottom of the sand with a siphon, and suck out the fish feces and residual bait in the sand.

3. Change the water frequently, 1 5 cylinders of water are suitable.

4- Add nitrifying bacteria in an appropriate amount to speed up the establishment of a nitrification system.

5- Moderately reduce feeding.

The fishy smell of the fish tank should be cleaned to change the water, the fish can be fished into another tank or container, and the cleaning can be cleaned with white vinegar to save trouble and effort, and finally the fish tank should be rinsed, you can put the water and fish, please!

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

The treatment methods for fishy smell in the fish tank include stopping eating, changing water, bursting oxygen, and gradually cleaning or replacing the filter material.

1. Fasting.

Stopping feeding, reducing the amount of fish excretion, and reducing the pressure of filtration, are good for the re-formation of the nitrifying environment, and after the nitrification environment is established, the nitrifying bacteria work normally, which is a key step to overcome the wateriness.

2. Change the water.

The purpose of the water change is very clear, continue to dilute the fishy water with new water, and at the same time ensure the survival of nitrifying bacteria and the normal and stable operation of the nitrification environment, so as to further solve the problem of wateriness.

3. Oxygen burst.

Oxygen explosion is also for the restoration of water quality, through the explosion of oxygen to increase the dissolved oxygen in the water, more oxygen supply to the fish, improve the state of the fish at the same time, but also improve the efficiency of nitrifying bacteria, because nitrifying bacteria are also aerobic.

4. The filter material is gradually cleaned or replaced.

Cleaning the filter media, or replacing the old filter media with new filter media, better play the role of filtration, improve the efficiency of physical filtration and biochemical filtration, especially biochemical filtration, is the key to deal with fish tank fish.

The solution to the fishy smell of fish tank water is to strengthen filtration and additionActivated charcoal, change the water frequently, reduce feeding, clean the fish tank filtration system, etc.

1. Strengthen filtration

If your fish tank or fish pond is not well filtered and the nitrification system is not perfect, it will cause a lot of ammonia to accumulate in the fish tank.

Fish excrement or food debris is released), if there is a foul smell, it is very serious and may cause your fish to die. 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

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

3. Change the water frequently

If there is a peculiar smell caused by too many fish farming, then reduce the density and then change the water frequently to improve. It is to change the water by one-third every 3-7 days. To change the water, you must change the tap water at the same temperature as the fish tank, and the temperature difference should not exceed 3 degrees, preferably the tap water that has been dried.

4. Reduce feeding

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.

5. Clean the fish tank filtration system

Clean the fish tank filtration system, wash half of it first, and then a week later.

Wash the other half again to avoid nitrifying bacteria.

Collapse of the microflora.

Change the water, the fishy smell of the fish tank is heavier, you can directly change the water to reduce the fishy smell, and you need to change the water every 2 or 3 days in the later stage; Strengthen filtration, the fishy smell of the fish tank is strong, the filtration system in the tank can be strengthened, nitrifying bacteria can be cultivated, and ammonia nitrogen can be converted into nitrate; Reducing the amount of food can reduce the amount of food to avoid the production of ammonia nitrogen after the food is fermented at the bottom of the tank.

The fish tank has a fishy smell, which can be solved directly by changing the water. Changing water is a very important process in the process of fish farming, regular water change can effectively improve water quality, reduce the content of harmful substances in the water, and also reduce the fishy smell in the tank. Note that the water should not be changed too frequently, generally every 2 3 days, change one-third of the water in the tank, to avoid affecting the normal growth of the fish.

The fishy smell in the fish tank is too strong, which may be caused by the high ammonia nitrogen content in the tank, and the ammonia nitrogen content in the tank can be reduced by filtration. Nitrifying bacteria can be cultivated in the tank, and the nitrifying bacteria can convert ammonia nitrogen into nitrate, which can avoid causing harm to fish.

The ammonia nitrogen content in the water is too high, which may be produced by the decomposition of organic matter, which is mainly used in fish food, so in the later feeding process, it is necessary to strictly control the amount of feeding, and it is not suitable to feed too much at one time, so that the fish can be eaten within 3 5 minutes. After each feeding, it is also necessary to clean up the food residue left at the bottom of the tank in time to reduce the growth of bacteria.
