the muddy water in the fish tank? If the water in the fish tank is always muddy, you need to change the water regularly. In order to maintain water quality, it is better to install filtration equipment in the fish tank. Good filtration can filter out impurities in the water, absorb harmful ions, and control the number of microorganisms, so that the fish tank can maintain a certain balance. It should be noted that the flow of filtration is usually related to the size of the fish tank, ensuring that the water can be circulated 7-10 times per hour.
? 1. High feeding density: The fish tank water is turbid, which usually has a great relationship with the feeding density. If there are too many fish, the water in the fish tank is easy to be turbid, mainly because of the large amount of excretion, the water quality is difficult to maintain, so it is necessary to reduce the density, change to a larger fish tank, or reduce the number of fish.
2. Feed too much: Fish need to be fed, but the amount of feeding should also be paid attention to. If too much is fed, the residual bait in the water will also promote microbial reproduction, thus making the water turbid. In view of this situation, it is necessary to control the feeding at ordinary times. If the feeding is less, the water quality will naturally go up. Usually, each feeding should ensure that the fish are finished within 3-5 minutes, and those that are not finished need to be cleaned up.
3. The number of water changes is small: fish farming needs to pay attention to water changes at ordinary times. If the number of water changes is too small or the amount of water changes is small, the water quality will not be improved, and the water body will become turbid. Therefore, the cycle of water change can not be too long, usually once a week, each time can change about a quarter of the total amount of water.
