Eheim Classic 250 2213 Aquarium Filter Pad - 3 Pack Replacement Media for Fish Tank Canister Filters | Perfect for Freshwater & Saltwater Tanks

Eheim Classic 250 - 2213 Filter Pad

Fine filter pads for mechanical and biological filtration

The porous material becomes evenly soaked with water and traps small dirt particles. After a short start-up period purification bacteria, which provide intensive biological decomposition of harmful substances, colonise the specially structured pad.

The fine filter pads are reusable many times over. To clean them simply rinse and squeeze out, so that the bacteria cultures are not completely destroyed.
