What s the deal with the fishy smell on the water surface of the fish tank? What should I do?

There is always a fishy smell on the fish tank, indicating that the water quality in the fish tank has deteriorated, so it is necessary to change the water in time and reduce the ammonia nitrogen content in the water.

There is a fishy smell in the fish tank, which may be because there are dead fish and dead aquatic weeds that cannot be fished out in time, breeding a large number of bacteria, resulting in a foul smell in the water, and the need to change the water every day.

It means that the water quality is very bad, and there may be some nitrifying bacteria in it. You have to change the water in time, disinfect and sterilize in time, and clean the fish tank in time.

It is normal for the fish tank water to have a faint fishy smell. Fish will have a little fishy smell, as long as the taste is not strong and the water is not turbid, there is no problem. If the water is turbid, it means that there is a problem with the water quality, and it may be that the ammonia nitrogen content exceeds the standard, which will cause poison to the fish, so it is necessary to change the water regularly to improve, or establish a good nitrification system, and you can also consider planting some aquatic plants.

1. Change the water regularly: If the fish tank is fishy, the best way is to change the water regularly. Changing the water is a necessary step in fish farming, not only to improve water quality, but also to increase dissolved oxygen, which is very beneficial to the health of the fish.

The interval of water changes is usually one week, and the maximum number of changes should not exceed one-third at a time.

2. Supplemental oxygen: If there are a large number of anaerobic bacteria at the bottom of the fish tank, it will also cause the water to smell fishy, and what needs to be done at this time is to supplement oxygen to inhibit their growth. The easiest way to fill oxygen is to use an oxygen pump to lead the outlet pipe to the cylinder, and open it for 24 hours.

3. Reduce feeding: There are too many organic matter in the water, and ammonia nitrogen is produced after decomposition, which is the main fishy smell, and organic matter is the fish food we usually feed, by reducing feeding, it can also reduce the fishy smell, and at the same time curb the deterioration of water quality.

1. How to get rid of the fishy smell in the fish tank.

2. What should I do if the fishy smell in the fish tank is very strong?

3. How to solve the water odor in the fish tank.

4. What should I do if the water in the fish tank smells fishy, and why does the water smell fishy?

1.If the water in the fish tank smells fishy, you need to change the water in the fish tank immediately.

2.The fishy smell in the water is mainly due to the decomposition of organic matter to produce a large amount of ammonia nitrogen, which is not only unpleasant, but also affects the health of the fish, causes certain poison to them, and even leads to the mass death of the fish.

3.The content of ammonia nitrogen in the water can be reduced by changing the water, and attention should be paid to cultivating nitrifying bacteria during the daily feeding process, which can also avoid the fishy smell of the water.
