Felt Filter Sock with Plastic Ring

Replacement filter socks for the Innovative Marine SR series of tanks. 

Filter socks are a great way to polish the water and export nutrients at the same time.  For best results we recommend changing out filter socks ever few days to keep the detritus from breaking down and turning into nitrates.  Between filter socks and running a good quality carbon in a reactor, crystal clear water is easily obtainable.

All SR series tanks use the 4″ x 12″ Felt Filter Socks. 

Specs:

• High quality double stitched felt
