The filter materials of the fish pond mainly include activated carbon, medical stone, coral stone, filter cotton, natural cotton, brushes, and so on.
1. Activated carbon is a relatively important filter material, which has a strong adsorption function and can absorb many kinds of pesticide residues in the water, such as chlorine, pigments, ultraviolet rays, etc.
2. Maifan stone has weak adsorption but can release a large number of beneficial trace elements, which is of great benefit to the growth of fish and the hatching of fish eggs.
3. Coral stones have many gaps, which are suitable for biological filters in alkaline water bodies. There are many types of filter cotton and it is the most widely used filter material.
4. The filter cotton mainly plays the role of physical filtration, which can filter out fish and much other garbage in the water, but it needs frequent cleaning to ensure stable filtration performance.
5. Biochemical cotton is a relatively common filter material, which can absorb a large number of nitrifying bacteria and filter larger particles flocculated in water to improve its transparency.
6. The radioactive structure of the filter brush can effectively reduce the sound of water generated by the water cycle, initially filter the larger particles of impurities in the fish pond or aquarium, and increase the oxygen capacity in the water.
