• Biological Filter Media

    Biological Filter Media 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 LAV, SUBSTRAT und SUBSTRATpro

    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.

    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 and biopower are ideal for partial cleaning.
