Carbon Sponge Juwel Carbon Sponges absorbs odour compounds and turbidity as well as toxic compounds in your aquarium, leaving the water crystal clear. The fact that active charcoal in the form of a sponge is used 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.
There are 2 pads in each pack
Suitable for both freshwater and marine aquariums.

These pads should be changed out monthly to absorb chemicals and to polish the water to make it crystal clear.
