AquaClear biological long-term pond filter medium

The AquaClear is a purely biological long-term pond filter medium and ensures optimal pond filter utilization in the biological area. The AquaClear biological long-term pond filter medium has a large colonizable surface of 140 m² per liter due to its up to 66% porosity. Due to its density of 350 kg / m³ it is ideally suited for koi ponds. The AquaClear biological long-term pond filter medium is burned in a special process at 1200 ° C in the oven. The pores of AquaClear biological long-term pond filter medium are large enough to provide nitrifying bacteria with a large settlement area.
