Usually, it is necessary to reduce feeding, and excessive feeding is the main reason for the water body to become fat.
However, we should also pay attention to avoid light. The growth of moss can not be separated from sufficient light, and proper light can prevent its growth.
In addition, you can raise fish that eat algae or eat moss.
First, change the water regularly. The best way to avoid moss growing in fish tanks is to change water regularly.
Changing water can improve water quality, reduce the number of moss in water and remove some organic matter. Without these substances, moss will lack nutrition if it wants to grow.
However, you can't change the water often to prevent moss from growing. Changing water too often will irritate the fish.
Second, it is necessary to feed less fish, but too much feeding will also lead to water fertilization, so that moss will grow and reproduce.
Therefore, in order to prevent the growth of moss, it is best to start from the source and reduce the total amount of breeding.
Generally, feed it three times a day, and you can eat it within 5- 10 minutes each time. Don't feed too much at once.
Thirdly, the growth of mosses that are properly protected from light is also related to light. If you want to control its quantity, you can also start from this aspect.
Don't let the fish tank see the light for a long time. It's best to put it in a dark place indoors. You can prepare a special aquarium lamp in the tank to fill the light, and it is enough to turn it on for 4- 10 hours every day.
Fourth, raise algae-eating fish If you raise some algae-eating fish in the fish tank, you can also avoid the growth of moss, such as hairy rats, elf fish, black Mary and so on. However, it should be noted that some fish only eat algae when they are young, so they need to be fished out when they grow up, and some fish only eat algae, so they need to be fed algae feed after the moss disappears.
