It is generally impossible for the water in the fish tank to recover by itself. The reason why the water is white and muddy is that the nitrification system in the tank collapses and a large number of nitrifying bacteria die. This kind of water is no longer suitable for fish farming. It is best to fish out the fish in time, otherwise it will be poisoned by ammonia nitrogen and even die in large numbers. Want to avoid this situation, the best way is to change the water regularly, so that the water quality can be maintained, and at the same time, it is easy not to clean and replace the filter materials.

1. Change water properly: For the white and turbid water body, the best way is to change water. Pump out part of the old water in the cylinder, and then inject new water. No matter what kind of fish tank, it is necessary to change water regularly. If the fish tank is small and the water quality is poor, it will be changed frequently. If the fish tank is large and filtered, the water change period can be longer.

2. Strengthen filtration: Besides changing water, filtration can also improve water condition and avoid rapid deterioration of water quality. If you want to strengthen filtration, you can change a water pump with higher power to speed up the circulation of water body, or clean the filter cotton, but you must wash it with the original tank, because the new water washing will destroy the nitrification system.

3. Reduce feeding: The water body will be white and muddy, or because of the high content of organic matter, which will allow microorganisms to multiply in large numbers, and the source of organic matter is the fed fish food. By reducing feeding, the water body can also be prevented from becoming turbid, which is helpful to the maintenance of water quality.
