Biological Filter Media
The main task of biological filter media is to offer the best colonisation conditions for the bacteria cultures, so that after a short time a bacteria lawn develops. The bacteria feed on dirt particles of all kind and convert substances critical for the aquarium. After the first cleaning process by the mechanical filter media (e.g. EHEIM MECH or MECHpro) the biological filtration is the most important. It provides for clear, healthy water and stabile water values. That’s why we have invested a lot of research work into the development of biological filter media.
EHEIM SUBSTRAT
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
m² 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.
