Instantly increase your sump's filtration capacity by adding this easy-to-install Filter Sock Holder by Fiji Cube. Designed to reduce noise and increase mechanical filtration, water passes from your aquarium drain into the filter holder compartment, where it then flows through either dual filter socks (included) or filter floss (sold separately) to remove ammonia-producing organic wastes. Adding this mechanical filtration step is crucial for protecting your pump motors from becoming damaged by sand, crabs, and snails that may make their way from your aquarium into your sump system.
