The white mist of fish tank water shows that the water quality is deteriorating, and it is very likely that the nitrification system collapses. In view of this situation, it is necessary to re-cultivate nitrifying bacteria and establish nitrification system. The method of culture bacteria is very simple. It is necessary to prepare a special culture liquid and pour it into a fish tank, which is usually added once a week. Pay attention to turning off the lights during the cultivation of bacteria. The dark environment is more helpful for its growth, and at the same time, it is necessary to explode oxygen to accelerate its reproduction.

1. Change water regularly: The simplest way to make white water clear is to change water regularly. Usually, the water should be changed once a week, but the period of water change can be shortened according to the water quality, but it should not be changed too frequently, so that the water quality will fluctuate greatly, which is also very unfavorable to the health of fish.

2. Enhance filtration: Besides changing water, good filtration can also improve water quality. The purpose of filtration is to filter out impurities in water, and nitrifying bacteria can also transform ammonia nitrogen, thus keeping the water clear. It should be noted that if the power of the water pump is not enough, the filtering effect will be weak, which requires increasing power. Every once in a while, check the filter cotton to see if there is any blockage. If the blockage is blocked, clean it with the original tank water.

3. Reduce feeding: The reason why water becomes white is usually because there are too many organic matter, which leads to a large number of microorganisms. By reducing organic matter, water turbidity can naturally be prevented, so it is necessary to control feeding and reduce the content of organic matter entering water from the source.
