What if there is moss in the fish tank?

1, there is moss in the fish tank. You need to take the fish out of the tank and put it in other places before cleaning the fish tank. There are two cleaning methods, one is to brush with a brush, pay special attention to the corners, and clean them all. Another method is to use algaecide, but it will not take effect immediately, and it will take some time. In addition, no matter which method, after cleaning, you need to open the can again to extract water.

2, reduce light: moss in water is different from that on land, they will grow faster where there is light, so you can put the fish tank in the shade to avoid direct light. If there is a light in the cylinder, do not turn it on for a long time.

3. Change water regularly: Changing water every once in a while can also effectively prevent the growth of moss. Usually it can be changed once a week, and the amount of water changed is between one quarter and one third, which can reduce the waste in the water and reduce some nutrients beneficial to its growth.

4. Eat fish: If you decide that cleaning is too troublesome, you can also raise some fish that eat moss. Goldfish in cold water fish is a good choice, and tropical fish have more choices. Many small tropical fish eat moss, such as peacock fish, moonlight fish, black Mary fish and so on. In addition, some fish of Silurus also have the habit of eating moss, such as blue dragon and lily fish. And you can also choose a scavenger or a rat fish. It should be noted that there are certain risks in polyculture, and it is necessary to ensure that they will not fight with each other.
