- Felt Filter Sock with Plastic Ring - Innovative Marine
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
The best! By Elizabeth on 7/23/2019Elizabeth would recommend this product to a friendThe IM 7” filter sock is the least expensive sock I can find. The quality is superb. This sock doesn’t have that stiff, weird coating on the inside. It’s smooth and clean... not stiff at all. It washes beautifully and looks good as new. Don’t waste your money on bargain socks... I’ve tried many of them. This one is the best I’ve used!

GREAT FILTER SOCK By Henhen on 9/13/2017Henhen would recommend this product to a friendI purchased 10 filter socks 2 or 3 times a year for my two Innovative Marine reef tanks. They work and fit perfectly. I have tried other filter socks but I only buy these from now on.
Work so well I Bought 10 more By RobertP on 3/14/2017RobertP would recommend this product to a friendWhat can I say they work really well. Threw them in the washing machine and laid them out to dry and they are like new.

Will the 4" x 12" sock work with the CPR sockit?
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.
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!
