Working principle:
The biochemical sponge filter uses the air pump as the power source to improve the dissolved oxygen and bacteria in the water. It combines mechanical filtration and biological filtration principles and uses multi-level filtration to cultivate high-density nitrifying bacteria to achieve cleanliness and good water quality stability. It is suitable for all kinds of Ornamental fish breeding, breeding, and young fish cultivation, especially for colorful angelfish, small fish, and fry.
Advantage:
●Increase the amount of dissolved air in feeding water
●Save power
●It can be matched with the cylinder, externally mounted, and the upper filter can be used for pre-exquisite filtering
●Cylindrical biochemical cotton has a comprehensive filtering effect without dead ends
●Multi-layer sponge design, can be cleaned continuously, moving the tank will not affect the water quality
