the fishy smell of the fish tank? If the fish tank has fishy smell, you need to change the water immediately, and clean up the dirty things in the tank at the same time. In the daily feeding process, we must pay attention to observation, if there are dead fish, it needs to be fished out in time, otherwise it will rot and cause odor in the water body. At the same time, attention should be paid to the establishment of nitrification system to reduce the ammonia nitrogen content in the water body, which also helps to solve the fishy smell of the fish tank.
? 1. Ammonia nitrogen exceeds the standard: Most of the time, the fishy smell of the fish tank comes from the water. If the ammonia nitrogen content of the water body is too high, it will emit a peculiar smell. The reason for this is that there is no good nitrification system in the tank, which requires regular addition of nitrifying bacteria to improve water quality.
2, the fish is ill: If the fish is infected with the disease, thus causing the body surface to rot, it will also cause the fishy smell in the water. In view of this situation, it is imperative to treat the fish, but it is best to isolate them to avoid infection of healthy fish, while the original tank should also pay attention to changing water, so as to maintain clean and hygienic water quality.
3. Water source problem: If there is a problem with the water source, it will also increase the fishy smell of the water body. But generally this possibility is relatively small, because household fish farming uses tap water, which contains no other harmful substances except residual chlorine, and can also dissipate residual chlorine by drying and other methods.
