Eheim Carbon Aquarium Filter Foam Pads - 3 Pack

Cut to form, these specially structured media take on the job of co-ordinated cleansing. They are evenly permeated by water and mechanically stop both coarse and fine particles.     

The carbon reacts by absorbing. It holds dissolved substances on its surface and removes them from the water cycle. 

They can only be used for short periods of time (up to 4 weeks) in order to prevent pollutants from releasing and re-entering the water cycle.
