Classification of filtration systems for koi ponds

Before raising fish, knowing that your fish tank has a powerful filtration system can save time, effort, and effort in raising fish, making it easy to raise fish and enjoy beautiful scenery. Everyone knows that the fish in the fish pond will turn black and smell after being kept for a long time. Then we need to have a thorough understanding of these filtration systems.

1. Bottom inlet system - Bottom pollutants, organic matter, leaves, sludge, etc. enter the filtration system through the inlet system.

2. Facial water storage system - stores all floating dust and tree leaves on the water surface into a filter

3. Sewage sedimentation system - the process of sewage entering and settling for a period of time.

4. Physical filtration system - blocking fish excrement, allowing organic matter from fish excrement to naturally remain in the filtration material.

5. Pu Filter Shi Biochemical Filtration System

The system has fast biofilm formation, well-developed biofilm, and is easily absorbed and degraded by organisms. It has a rich biological community, forming a long food chain of fungi, algae, protozoa, and metazoa. The organic matter and nutrients contained in aquaculture water migrate and transform through contact with numerous food chains in the biofilm, degrading into final products such as CO2, H2O, NH3-N, NOx N, PO4, etc. At the same time, they are removed through processes such as nitrification, denitrification, and assimilation, achieving high purification efficiency; At the same time, the universal filtration brush biofilm in the system can efficiently consume bacteria, algae, and protozoa, generate metazoa, and significantly reduce biomass, resulting in very little remaining sludge and no sludge bulking, only 1/20 of the activated sludge process. It can discharge sludge once every 1-2 months, and the amount of sludge shedding is very small. It only requires simple treatment and restoration, with low investment, low operating costs, long service life, and easy installation and maintenance.

6. Mineral decomposition system - after purifying water, it can increase the precipitation of minerals in the water by importing biochemical stones and other substances. The mineral content in aquaculture water is high, and the color of fish is bright and beautiful.

7. Sterilization system - adding a protective layer to the living environment of fish can better disrupt the growth of microalgae in water. Maintain clear and bottomless water quality.

8. Aerobic aeration system - increases the dissolved oxygen in water, ensuring that fish are not oxygen deficient. Maintain an efficient ecological chain.

9. Water circulation system - ensures the flow rate and flow rate of pool water through the filtration system based on the size of the pool.

10. Bottom sewage system - normal circulation of filtered water. After nitrification and denitrification. After a period of time, the dirt can be discharged in a timely manner.

11. EM bacteria can effectively inhibit the growth of various algae, decompose and oxidize excreta, residues, and nutrients, and have a positive effect on the health of fish.
