Filter Media Mesh Bags - 10Pcs - 15 x 20cm test strips Mechanical Filtration: Three foam discsDescription: If you're running a canister filter with multiple types of media, filter media mesh bags are one of those small additions that make a genuine difference to how easy your filter is to maintain. Without them, loose media like activated carbon, bio balls, ceramic rings, or filter floss can shift around inside your filter baskets, mix together, and become difficult to remove cleanly when it's time to rinse or replace a specific media type.
