Hybrid Filter Sock 4" (10 cm diameter) – 25 cm long

The Hybrid filter sock combines a denser filter material with a coarser mesh structure at the top. This design effectively collects loose debris and particles from the water, while the more open top helps reduce the risk of overflow caused by sock clogging.

The filter sock is suitable for mechanical filtration in saltwater and freshwater aquariums and sumps. Its removable design makes it easy to replace, clean, and maintain the sock.
