the fishy smell of fish tank water? If the fish tank water has fishy smell, it is necessary to change the water immediately and reduce feeding at the same time. The reason for the fishy smell is that the ammonia nitrogen content is relatively high, which not only smells bad, but also does some harm to fish. Therefore, it is necessary to improve the water quality by changing water. It should be noted that the amount of water should not be too large, so as not to stimulate the fish body and cause harm to it. In addition, we should start from the source and control feeding to reduce the output of ammonia nitrogen.
1. Change the water too little: The reason why the water has a fishy smell is that the water is not changed frequently at ordinary times, resulting in an increase in ammonia nitrogen in the water, so it is necessary to do a good job of changing the water at ordinary times. Usually every five to seven days, it can be changed by a quarter or a fifth each time, and the temperature should not fluctuate too much before and after the water change.
2. Excessive feeding: Usually, the ammonia nitrogen in water is mainly produced by the decomposition of organic matter, and the source of organic matter is the daily feed. The greater the amount of feeding, the higher the content of ammonia nitrogen. Therefore, reducing feeding can also avoid the fishy smell in water.
3. Too much density: The more fish are raised, the more excrement they produce, which will also lead to the fishy smell of the water body. In this case, the best solution is to reduce the feeding density, change to a larger tank, or raise fewer fish, so that the fishy smell can be reduced or eliminated.
