Biological filter mass (150g) similar to EHEIM substrate pro made of spherical ceramic.
Bio-filter medium with good volume utilization, good service life and high degradation capacity.
This biological filter mass consists of spherical ceramic. The spherical shape allows a high bulk density. Thus, the volume in the filter (filter baskets or modules) can be fully utilized. In addition, the optimized surface of the beads ensures intensive settlement of the important purification bacteria. It forms a dense bacterial lawn and is suitable for both freshwater and seawater.
Advice:
Never clean or replace the entire biological filter material in one operation (never too thoroughly). The bacterial cultures must not be completely destroyed, otherwise the resettlement will be delayed. For partial cleaning, the filter baskets in external filters and the filter modules in the internal filters aquaball and biopower are ideal.
