Good question. All of our filter socks are 200 micron filter socks!
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.
This will be the 4x14 models with the plastic rings :-)
Is there any O ring I can use or, can I put a heavy rock in the bottom of the sock to hold them tighter to the opening?
The 4x 8 will work great additionally we have used the 4x14's as well which allow for a little more time before changing.
We are not familiar with the CAD lights sock size. As long as the hole for the filter socks is 4" exactly our filter socks will work great! Feel free to let us know if you have any further questions!
These filter socks have a lip which makes the inside diameter not very important for measurement. These will fit inside of a 4" diameter hole perfectly however! Feel free to let us know if you have any further questions!
This will not work in the red sea reefer tanks unfortunately. The only socks we are aware of the if the socks directly from Red Sea. Feel free to let us know if you have any further questions!
You can put any type of media you choose into the filter socks, however for a media sock, we would suggest using the mesh socks over the felt, since little particles of media, like getting stuck in the felt socks and become a bit harder to clean over time. The mesh socks handle loose media much better while allowing for more flow through them. The felt socks are best for water polishing.
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?
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.
Either of the 4" filter socks will do the trick. I personally prefer to use the 14" even if its a bit long.
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
My Favorites By Evan on 3/15/2017Evan would recommend this product to a friendI only started appreciating these socks when I switched to a sump that doesn't fit them. I especially like them after my monthly maintenance, when I like to stir up the sand bed and blow detritus out of the rocks. The tank water turns filthy, but overnight, these socks polish the water to sparkling clean. No mesh sock I've ever tried comes close.
I miss you, trusty BRS felt filter socks...

BRS Felt Filter Socks Work By Rick on 2/23/2017Rick would recommend this product to a friendthe BRS Filter sock with plastic ring do a great job of the start of the filter process in my sump
Great sock filters By Lou on 2/7/2017Lou would recommend this product to a friendI bought 2 extra socks for my CPR SOCKIT 4” SOCK-it Filter Sock Holder which I bought here at BRS. These socks feel strong and sturdy and fit so well on my sock holder. I definitely recommend buying these. They are not too difficult to clean either. I just turn them inside out, wash them out with hot water and then throw them in a bucket full of bleach and hot water. Leave it in for a few hours and they are white once again, like new.
Trigger Systems Emerald Sumps By jeffrey on 1/25/2017jeffrey would recommend this product to a friendI ordered a couple of extra felt socks when I purchased the Trigger Systems Emerald 34 Sump. The sump came supplied with 4 X 14 felt socks which to me seem to long. The socks seems very well built and I will have to wait and see what happens over time. I will be getting more of the 4 X 8 Felt socks so that I can be better at cleaning them out regularly.
HEY NICE SOCKS By CJ on 1/17/2017CJ would recommend this product to a friendGreat filter socks.

Clean Your Socks! By Bloody Knuckles on 12/22/2016Bloody Knuckles would recommend this product to a friendI love the socks!
Use. Remove. Dry. Soak in hydrogen peroxide a day or two. Rinse/spin in washing machine. Clean, white socks.
I will try to update with longevity results.
Can't Beat Em By DrChop on 12/8/2016DrChop would recommend this product to a friendI bought the 4"x8" to use in my diy 5.5g sump/refugium I built for my JBJ 28g Nano Cube...These things are PERFECT! The fact that the stand wouldn't accommodate much for a sump, leading me to use a 5.5g glass tank, left me scrambling for the right felt sock. These are perfect in length, more rigid than the typical socks, so they hold upright much better. Ordering a few more now to make swaps and cleanings seamless. Another top quality item from BRS
Favorite Socks By Eric on 12/7/2016Eric would recommend this product to a friendThe outer surface is singed which makes the socks hold up better to repeated rinsing/washing
They work. By LiveBait58 on 10/22/2016LiveBait58 would recommend this product to a friendNice socks that work great and hold up well in the washer. I'll continue to buy them.
Awesome Socks By Chad on 10/17/2016Chad would recommend this product to a friendGreat socks but the plastic ring scratches the hell out of my ankle. :)
Seriously though they work wonders at keeping stuff from recirculating in the tank and keep my water polished. Just remember to change them out often. I got 3 sets for ease of use.
