1. Porous structure improves the fluency of water and greatly increase the breeding of nitrifying bacteria to establish a stable nitrification system.
2. The inner layer provides anaerobic bacteria to react effective nitrification. The filter material is made by advanced ceramic materials and does not cause dust to water pollution while the neutral material will not have an impact on the PH quality.
3. Lock water effect of nitrifying bacteria and not easy to die.
