The Juwel BioCarb Filter Media for Aquariums is a range of cleverly designed carbon sponges that absorb odors, turbidity, and toxic compounds in your aquarium, leaving the water crystal clear. The use of active charcoal in the form of a sponge ensures even flow conditions for the filter medium, resulting in a very large and thus highly effective surface. Because of these properties, JUWEL charcoal filters are ideal for filtering out residual medication after treating your fish. Each pack contains two Charcoal sponge filters.
