Juwel Biocarb Carbon Sponge Large

The Juwel BioCarb Carbon Sponges absorb odour compounds and turbidity as well as toxic compounds in your aquarium, leaving the water crystal clear. The sponge format of the active charcoal guarantees even water flow within the aquarium filter media, creating a very large and therefore highly effective surface. Due to these characteristics Juwel charcoal filters are also perfect for filtering out residual medication after treating your fish.
