Standard bio-filter medium with large colonisation area for bacteria cultures and high efficiency SUBSTRAT can be layered in one or more layers. It is a highly porous filter material made from sintered glass. The surface structure offers the important purification bacteria excellent colonisation conditions. The colonisable area amounts to 450 m
per litre. EHEIM SUBSTRAT is suitable for fresh and marine water, is washable and can be reused.
- Standard bio-filter medium
- Highly porous material made from sintered glass
- Excellent conditions for bacteria cultures
- Reusable (rinse carefully to clean)
- Suitable for fresh and marine water
Tip: Never clean or change all the filter media together in one operation (and never clean too rigorously). The bacteria cultures must not be completely destroyed, otherwise re-colonisation will be retarded. The filter baskets in the external filters and filter modules in the internal filters aquaball an biopower are ideal for partial cleaning.
