Juwel Carbax
The Juwel Carbax filter medium sets new standards in aquarium filtering with active charcoal. Carbax is a highly effective, hard coal based granulated active charcoal that has been specifically developed for cleaning and decolourisation of water-based liquids. In contrast to conventional charcoal filter media, with Carbax, the entire active charcoal grain is completely activated and not just the grain surface.
