Tideline 3" Mesh Filter Sock

This replacement mesh filter sock is designed for Tideline 20.5G Peninsula and 21.4G Cube AIO aquariums. Filter socks provide convenient mechanical filtration by removing excess food, detritus, organic waste, dust, and other particulates from the water column. By reducing these particulates, they help lower ammonia levels and other undesirable substances while protecting pump motors from larger debris such as sand, crabs, or snails. Regular use promotes crystal-clear water and a healthier aquarium environment.
