*Box contains 2 charcoal sponges 
 
JUWEL Carbon Sponges absorb odour compounds and toxic compounds in your aquarium, leaving the water crystal clear. Active charcoal in the form of a sponge guarantees  even flow conditions for the filter medium, 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.
 
They are available in three sizes, in packs of two.
 
Suitable for use in freshwater and saltwater aquariums
