The reason why the fish tank will turn green is because of the proliferation of Chlorella in the water. This is a common algae, itself is very small, when the large number of water will turn green. Although it does little harm to fish, or even no harm, but after the water turns green, it will still affect the viewing, so it is best to clean up in time to make the water clear again.
1. Appropriate shading: As mentioned above, the fish tank green is caused by the outbreak of algae, and the growth of algae can not be separated from a certain amount of light, through shading can curb its growth trend. Of course, shade is not completely invisible, but to avoid direct light in the fish tank, appropriate light for the growth of fish is also helpful.
2. Reduce feeding: The growth of algae is also related to the nutrition level of the water body, and the source of nutrition for the water body is the fish food that is usually fed. Whether it is the fish food that has not been eaten or the fish feces excreted after being eaten, it will become the nutrients needed for its growth. Therefore, reducing feeding can also cut off its source of nutrition, thus making the water clear.
3. Raising algae-eating fish: Green water is different from other algae, and it is very difficult to clean it artificially. However, some algae-eating fish can eat it, such as moss rats, elves, and so on. Of course, in addition to fish, black-shell shrimps and snails also have the characteristics of eating algae. You can improve the water quality by raising these animals.
