Generally, the green water will not be filtered out unless it is eliminated by some special algaecide. The reason why there is green water is that there are a lot of Chlorella in the water, which is almost harmless to fish and can be used as fish food. At the same time, it can release oxygen through photosynthesis, which is helpful to the breathing of fish. It can be said that it is a kind of water suitable for fish farming, but it does not look very beautiful.
1. Reduce the illumination: If you want to make the green water in the fish tank clear, you must first control the time of illumination. If the algae is in an environment with insufficient illumination, its growth and reproduction will be limited, and the algae in the tank will slowly die out. It should be noted that reducing light is not invisible, and fish also need a certain amount of light to develop better.
2. Control of feeding: The main reason for the outbreak of algae is that the water body in the tank is in an eutrophic state, that is, too much feeding at ordinary times leads to a large amount of excretion of fish. These feces are the nutrients needed for the growth of algae. By controlling the amount of feeding, the fat water can be thinned down, thus curbing algae.
3. Pay attention to changing the water: by changing the water frequently, the green water can also become clear. But this method often causes some harm to the fish, because the original ecological cycle in the fish tank is broken, if there are no other measures, the fish may also die, so it should be used with caution.
