Mechanical Filter Pads maintain even water flow while trapping coarse particles as well as the finest particles. Beneficial bacteria gradually colonize the special coarse foam material to provide additional biological filtration. Carbon Filter Pads have an adsorptive effect, trapping dissolved aquarium pollutants on the filter surface and removing them from the water column. Coarse/Fine Pad Set includes 4 Fine Filter Pads (White) and 1 Coarse Filter Pad (Blue). For use in ECCO Pro. Please click on "More Information" for filter media maintenance. | ||||||
