Pro Clear Aquatic Systems Sock Canister Filter 4in

The Pro Clear Aquatic Systems 4" Sock Canister will make you forget about filter socks. This product is designed to replace filter socks in an EcoReef Sump. Each Sock Canister comes with a sponge that can be easily removed with the included sponge remover. The included sponge will help pick up large debris while allowing bacteria to colonize and pods to pass through. These canisters are large capacity and have room for other media to be added. At this time the 4" Sock Canister does not work with the RedFlex Line of Sumps.
