The fish tank water is very fishy, indicating that the water quality in the tank is deteriorating and the content of ammonia nitrogen is relatively high. In view of this situation, the best way is to change water in time, which can quickly improve water quality and reduce ammonia nitrogen content in water. In order to prevent ammonia nitrogen from continuing to increase, it is better to stop feeding for a period of time and control the feeding amount at ordinary times. In addition, attention should be paid to the cultivation of nitrifying bacteria, which can convert ammonia nitrogen and help to maintain water quality.
the fishy smell of fish tank water 1. Keep filtering: The most direct way to remove the fishy smell of fish tank water is to keep filtering. Filtration can keep the water flowing, thus better maintaining water quality, while also establishing a nitrification system, with enough nitrifying bacteria, ammonia nitrogen can also be converted into nitrate, thus avoiding fish poisoning.
2. Change water regularly: Fish farming must change water, which can reduce the content of harmful substances in the water, thereby improving the water condition. It is usually changed every five to seven days, and a quarter of the water is changed each time, which can also avoid excessive ammonia nitrogen content in the water, thus reducing the fishy smell of the water.
3. Reduce the feeding: The ammonia nitrogen in the water is mainly decomposed from the organic matter, and the source of the organic matter has two parts, one is the residual bait that has not been eaten, and the other is the feces of the fish. By reducing the feeding, the content of the ammonia nitrogen can be controlled, so as to avoid the fishy smell of the fish tank water.
