What steps do fish pond filtration generally need?

A. Physical filtration: Generally, rotary drum filter is adopted, featuring low energy consumption, large circulating flow and full automation. Its main function is to remove leaves and suspended matter in water (skimmer) and remove fish manure, sludge and other sediments at the bottom (bottom filter).

B, biochemical filtration: The main purpose of biochemistry is to reduce the content of dissolved organic matter in water, so as to prevent the water from deteriorating and stinking, prevent the water from eutrophication, and cut off the nutrient source of algae outbreak. Biochemical filter materials are generally divided into sponge and elastic brush. The material is mainly considered from the surface area, among which sponge has a large specific surface area and can absorb some fine particles in water, so it is an excellent biochemical material.

C. Sterilization and disinfection: The purpose is to kill some harmful bacteria, viruses and algae in water.

In terms of process flow, physical filtration, biochemical filtration, sterilization and disinfection can fully meet the needs of fish ponds in koi fish.
