Mini Filter:
Function: The biochemical sponge filter uses the aeration pump as the power source, the gas lift power is large, there is no noise, and the dissolved oxygen in the water is improved;
Working principle: Combine the principle of mechanical filtration and biological filtration and use multi-layer filtration to cultivate high-density nitrifying bacteria to achieve cleanliness and good water quality stability;
Suitable for a variety of fish tanks: suitable for breeding and hatchling of various ornamental fish, especially for colorful angelfish, small fish, and fry.

The filter is composed of the following 5 parts:
