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. 



  • High quality double stitched felt
  • 200 Micron pore size
  • Pre-rinsed for instant use
  • Made in USA
  • Internal plastic handles for convenience

Will the 4" x 12" sock work with the CPR sockit?
Question by: Michael Eaddy on May 23, 2016, 1:02 AM
Great question! They should fit no problem :)

Will these socks (4x12 inch) work with the Red Sea Reefer 450? The original socks are 4x 10.5. I'm not worried about the length of the sock, only that your socks will fit within the sliding tray that Red Sea has incorporated in their sock filtration design.

Great question!
The IM filter socks will not work with the Red Sea tanks as their lip interferes with the ATO reservoir. The Red Sea filter socks will need to still be used. Feel free to let us know if you have any further questions!
