Filter Socks are used on overflows to remove small floating particles from aquarium water. This can dramatically improve water quality and reduce maintenance on filters that would otherwise become clogged.

  • 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.

Mesh Filter Sock are less effective than felt but clog less frequently. Plastic ring fits common sump holders.

Product Questions

Will these work for a Red Sea Reefer? Sourcing their socks is making me wish I went in a different direction tank wise.
Question by: Corey on Jul 22, 2016, 3:06 PM
Hi Corey,
The Red Sea Reefer Socks are 4.5" in diameter and most other filter socks including our BRS brand ones will just fall straight through. You may want to make an adapter plate to accept a standard 4" filter sock. You should be able to make an adapter out of a piece of acrylic and a wholesale.

can you wash and re-use these filter socks
Question by: Lester on Apr 2, 2014, 12:25 PM
Hey Lester,
You sure can! I personally think the mesh ones are a bit easier to clean then the felt, though you will probably get more cycles out of the felt as its a bit more durable material.
