★ PREMIUM QUALITY AND REUSABLE:

Solid construction and heavy duty stitching make these socks strong and durable so they can be CLEANED and REUSED NUMEROUS TIMES. You will receive eight 4 inch by 14 inch long felt filter socks with a 4-inch diameter plastic ring that will fit most sump holders.

★ IMPROVE WATER QUALITY:

Our filter socks have interlocking micro-denier felt fibers that are perfect for trapping uneaten food, waste excreted by livestock, decaying plants, detritus, dust, and other floating particulates. Changing filter socks regularly will increase water quality by removing solid organic compounds before they continue to break down and add additional nutrients (which can increase algae growth) to your aquarium water.

★ CUSTOMER AND PROFESSIONALS CHOICE:

Our 200 micron filter socks are BEST SELLERS - the TOP CHOICE for my clients as well as my aquarium service technicians and both chose 200 micron socks because they do not clog as quickly as smaller microns do, yet they help ensure crystal clear water.
