External Filter HW-302 Ceramic Rings 450g

Ceramic glass rings for internal and external filters. The filter media with mechanical filtration are used for removing suspended particles. The ceramic rings provoke a water turbulence in the filter basket due to their special form and large surface. Thus, floating particles deposit while sinking, and coarse dirt particles are removed from the water circulation.This filter material creates optimal conditions for filter bacteria which reduce nitrite peaks better than other filter materials.Due to their small size, ceramic rings can be applied even in the small components of internal, external, and cascade filters.Please also see our other spare parts.If you need help with a fault of your SunSun product, simply contact us.
