Juwel Aquarium Filter material Carbax Bioflow 8.0 Jumbo

The filter medium Carbax sets new standards in aquarium filtration with activated carbon.
Carbax is a highly effective, hard coal-based granular activated carbon, which was specially developed for cleaning and decolourising water-based liquids.
Unlike conventional carbon filter media, Carbax completely activates the entire grain of activated carbon and not just the surface of the grain.
Carbax thus binds discolouration, odours and toxic substances particularly quickly and for a long time and ensures crystal clear water in your aquarium.
