Filter socks are most commonly used in sumps to help trap free floating particles in the water that flows through the sock. The Red Sea felt filter socks are great for removing large pieces of free floating material from the water that flows through the sock. Felt filter socks are a thinner material than felt usually lasting a bit longer and easier to clean.
We do recommend having a few extra socks on hand and changing them ever couple days for best results. The Red Sea filter socks have a 225 micron rating to allow a majority of detritus to be collected while allowing smaller particles through. We have found with filter socks with a micron size below 150 can clog very quickly, where 200+ micron socks can last a few days before they are clogged.
Compatible with Red Sea Reefer and MAX-S series of tanks.
Please keep in mind Red Sea Filter Socks have a diameter of 4.5" where most traditional filter socks have a 4" diameter.
Not My Favorite By ParaDiddle777 on 9/21/2017ParaDiddle777 would recommend this product to a friendI wish the socks were a little wider so it would be easier to turn them inside out. If you use a piece of pvc pipe or a wooden spoon, it helps, but they are annoying to clean because of this.
Red Sea filter sock By Diver Down Reefer on 5/3/2017Diver Down Reefer would recommend this product to a friendVery well built filter sock. Fits in my Red Sea Reefer 425 xl well.
Expensive but worth it!! By BadabingNC on 3/7/2017BadabingNC would recommend this product to a friendI know these are the only ones that fit the Red Sea holders but these are much better than the typical BRS felt ones!! They do work better than the mesh ones but just like any felt socks, rinse wash with bleach and rinse again!!
Does what it is suppose to do By K-lisby on 11/22/2016K-lisby would recommend this product to a friendLike the quality of the sock, and it fits greatly into my rsm s500.
Catch a lot of the floating debris and therefor has to be changed/ washed often. I find it a little expensive...
