If the water in the fish tank is turbid, you can change it, so that the water quality can be improved quickly. Usually, fish farming needs to change water regularly, and usually relies mainly on filtration to maintain water quality. If the water is muddy just after changing, it means that the nitrification system in the tank has been destroyed, which requires re-culture of nitrifying bacteria. In addition, in the daily feeding process, we should pay attention to the feeding amount, and we should not feed too much, otherwise it will pollute the water environment.

1. The feeding density is high: The turbid water in the fish tank usually has a great relationship with the feeding density. If too many fish are raised, the water in the fish tank is easy to be turbid, mainly because of the large excretion and the difficulty in maintaining the water quality. Therefore, it is necessary to reduce the density, change to a larger fish tank, or reduce the number of fish raised.

2. Feed more: Fish farming needs to be fed, but the feeding amount should also be paid attention to. If too much is fed, the residual bait in the water will also promote the reproduction of microorganisms, thus making the water turbid. In view of this situation, it is necessary to control feeding at ordinary times. If there is less feeding, the water quality will naturally go up. Usually, every feeding should ensure that the fish are eaten within 3-5 minutes, and those that are not eaten need to be cleaned up.

3. Less water change times: Usually, fish farming needs to pay attention to water change. Too few water change times or small amount of water change can not improve water quality, and the water body will become turbid. Therefore, the period of changing water should not be too long. Usually, it should be changed once a week, and about a quarter of the total water volume can be changed each time.
