- BRS Felt Filter Sock with Plastic Ring
Better quality for half the price. By Ben on 10/29/2014Ben would recommend this product to a friendMuch better than the soft felt ones that came with my sump for half the cost. They catch more detritus and have a heavier, more rigid construction. They also held up 10x better in the wash than the original ones. I will be ordering more and tossing the ones that came with my proflex sump.
Great By Adam on 9/8/2014Adam would recommend this product to a friendGreat filter socks, traps a lot of crap, unbeatable price
Great value and filtering capacity. By Ojake on 9/7/2014Ojake would recommend this product to a friendBe sure to pre-rinse before use. I put all of my new ones in clothes washer and water only.
great socks By cheeshead on 9/3/2014cheeshead would recommend this product to a friendI think these are the best socks available. they don't bother my skimmer at all, and last as long as any other sock.
Does what it is supposed to do. By Glenn on 9/2/2014Glenn would recommend this product to a friendits a filter sock. Fits perfect in the BRS sock bracket. I do recommend washing them with just water in the machine before first use. The last batch I bought made my skimmer go nuts for two days. Probably some manufacturing residue on the felt. It calmed down fine after a couple days, and no harm done. (I did lose a Blenny a couple of weeks later, but I don't think it was related.). I change them out every 2 or 3 days, and keep a couple of the mesh ones handy for when I gone a week or more.
Good quality product By Jonathan on 9/1/2014Jonathan would recommend this product to a friendI was hesitating on buying this filter sock, I have been using the eshops brand of filter sock, after using BRS filter socks I will never use other brand. They are made of high quality and are extremely easy to clean and at a great price.
good sock for price By Liz on 8/13/2014Liz would recommend this product to a friendSeems to be identical to the CPR-brand sock that came with the CPR sock-it filter holder, at a lower price, so why pay more?
Cleans up well turned inside out in the washing machine on a cold cycle with no detergent.
Good filter sock By A on 7/16/2014A would recommend this product to a friendBuilt tough, I flip them inside out and wash them in the machine.
Filter sock rock By James on 7/1/2014James would recommend this product to a friendThese filter socks work great, I wash mine a couple times through and get great life and performance, at a great price

Awesome Product By Kashbu on 5/29/2014Kashbu would recommend this product to a friendI would definitely recommend this product
came up short By Tim on 5/29/2014Tim would recommend this product to a friendOrdered the 4 x8 and it is way to short. The first time I've been disappointed with something I've ordered from here. Not a true 8inchs at all, left me going to the LFS and paying more for the right size. I use this one to clean my carbon before adding it. Still love BRS.

What is the correct size for a aqueon #1 sump?
Bulk Reef Supply Hi Jason,
Either of the 4" filter socks will do the trick. I personally prefer to use the 14" even if its a bit long.
by Larry on June 12, 2014, @5:31 AM
I've been using the 8" socks with good results - their also very durable and machine wash well.
1) Is using bleach necessary when machine washing?
2) What's the best way to tell when these socks need to be replaced (because of age/wear and no longer effective)?
3) If I wait too long will that contribute to an increase in nitrates?
Bulk Reef Supply Hi Larry,
1) It isn't necessary (many people just use straight water) but bleach does a very good job of breaking down organics.
2)If they have holes worn thru them or if the stitching starts to come apart would be when I would start to worry about them :-)
3)If you leave them in the tank to long it won't be as effective. It is more of an opportunity cost, by leaving the sock in for too long you give a chance for detritus to contribute to the nutrients in the tank, whereas if you had changed it out you would have removed it from the tank before giving it the opportunity. In the end, there won't be any more nitrates then could have existed without it, but you missed your chance to prevent them if you don't change them.

I'm looking for a filter sock for my aqueon sump
Bulk Reef Supply Hi Hank,
This will be the 4x14 models with the plastic rings :-)
by Ken on June 3, 2014, @7:03 PM
I use the felt sock with the plastic ring and would like to know how people clean them.
Bulk Reef Supply Hey Ken,
Some folks just throw them in the washing machine when they collect enough dirty ones. Personally I turn them inside out and give them a good rinse and scrub by hand.
by David on September 4, 2013, @8:35 AM
What is the micron rating for these socks? Thanks
Bulk Reef Supply Hey David,
Good question. All of our filter socks are 200 micron filter socks!
by Don on November 19, 2013, @5:11 AM
How often do you normally recommend you change the filter socks? what is the best method to clean the socks? if soaking - in what solution?
Bulk Reef Supply Hey Don,
The more often you change them the better, that way you can remove the solids before they continue to break down and add additional nutrients to your water column. You want to avoid soaps when cleaning them but its pretty common for people to use unscented household bleach in water. Be sure to rinse them and all them to dry completely.
Filter socks come in mesh or felt and with a plastic ring or draw string. See below for differences and unique advantages.
- Mesh: Thin, doesn't clog as easily as felt
- Felt: Thicker, better at removing particles, but can clog faster
- Plastic Ring: attaches via ring that fits common sump holders
- Draw String: attaches directly to plumbing
- BRS recommends starting with felt socks and switching to mesh if they clog faster than desired.
Filter sock benefits:
- Regular use will result in crystal clear water most convenient form of mechanical filtration.
- Remove excess food, detritus, organic waste, dust and other particulates
- Convenient form of mechanical filtration
- Prevents larger objects like sand, crabs and snails from damaging pump motors
- Reduces ammonia and nitrate producing organic waste
- Increases filter life
