Eheim Carbon Pads for Professional Series:
Specially designed Eheim filter pads provide outstanding mechanical, chemical, and biological filtration. They maintain even water flow while mechanically filtering coarse particles as well as the finest particles. Beneficial bacteria gradually colonize the special foam material and provide additional biological filtration. Carbon Filter Pads have an adsorptive effect, trapping dissolved pollutants on the filter surface and removing them from the water column.
Includes three activated carbon foam pads. Fits Eheim Pro 3 Models 2071/2073/2075 and Eheim Pro 3E Canister Filter Model 2074.
Since adhering dirt particles cannot be rinsed out completely, the filter pad must not be used more than once. Insert new pad. After excessive use, the collected pollutants may detach again; therefore, the pads may only be used for short periods (one to two weeks).
