Felt Filter Sock with Plastic Ring - 100 Micron

Red Sea Felt Filter Socks are great for trapping detritus and free floating particles in your tank. Filter socks are washable for continued use and will help give your tank water that crystal clear look.

100 micron felt filter bags are designed to provide fine ‘polishing’ of water that is already low in particulate matter (mature aquariums).
