It contains medical stone, which can provide various trace elements to small fish tanks. The biochemical cotton filter uses an air pump as a power source. Using the suction provided by the air compression system, the biochemical cotton can capture the suspended solids in the water and return the filtered water to the fish tank as a biological filter. The hazardous waste is grown in the biochemical cotton. The nitrifying bacteria are biodegraded and transformed into harmless substances to fish, which are suitable for the breeding and breeding of various ornamental fish and the cultivation of juvenile fish, especially for colorful fairy, small fish and fry. Baby features 1. Increase the amount of dissolved air in feeding water. 2. No noise, save power. 3.
