Eheim Classic 250 Blue Foam Course Filter Pad Part No (2616131). Filter Mat (2 Pieces) for Eheim 2213 & Eheim Classic 250 Canister Filters.

Designed for mechanical and biological filtration. The porous material is penetrated evenly by the water and holds coarse and fine dirt particles. After a short break-in period, cleaning bacteria settle in the structured special foam, which ensures the intensive biological breakdown of pollutants. The mats can be used several times. For cleaning, you should only rinse and squeeze them out so that the bacterial cultures are not completely destroyed.
