Eheim BioMech 1 Liter

The Eheim bioMECH mechanical-biological medium acts as a dirt barrier when water passes through the filter. This specially designed pH-neutral material works well to hold back dirt particles from re-entering your aquarium. The unique pore structured surface attracts colonization for cleaning bacteria to remain, creating biological water purification which does not contain any water hardeners. Handily, you may wash and reuse this filter medium many times by gently rinsing and making sure the bacteria cultures do not get destroyed. This mechanical filter medium can be used with freshwater or saltwater aquariums, so sit back and watch how clean the bioMECH keeps your aquarium, leaving you and your aqua life completely satisfied.
