a small fish tank filter? First of all, choose the right type of filter. Not all filters are suitable for installation. Generally, only filters or filter cartridges can be installed. The upper filter should be installed on the top of the fish tank, and a submersible pump is placed in the tank, which can pump water into the upper filter tank and flow back into the tank after filtering layer by layer. The filter cartridge is external and can be placed next to the fish tank without occupying the inside position, but it is more troublesome to clean.
of filtration? 1. Physical filtration: Physical filtration is an essential part of filtration equipment. Its main function is to pump suspended particles in the water, such as residual bait, feces and fish metabolites, into the filter tank, which can make the water clear and greatly increase its ornamental value.
2. Chemical filtration: Chemical filtration usually uses various reagents, such as flocculants and algaecides, which are also used to improve water quality. Flocculants can adsorb impurities in water and sink to the bottom of the water, while algaecides can eliminate algae in the water, thus making the fish tank look more beautiful.
3. Biofiltration: Biofiltration is the most important part of all filtration. It is the complement of the ecosystem in the tank. Because microorganisms can decompose the organic matter in the water, but the ammonia nitrogen produced can not be eliminated, it will also cause toxicity to fish. Biofiltration is to convert ammonia nitrogen through nitrifying bacteria to avoid affecting the health of fish.
