Seachem Filter Sock 4" x 12" (4" Collar)

Seachem Filter Socks remove suspended particulates from the water column down to 100 microns, providing exceptional purity and water quality. These socks are built to last, with durable welded seams and a singed finish to reduce wear and prevent the reintroduction of debris to your aquarium.

100 Micron Rating. One micron is on millionth of a meter (or one thousandth of a millimeter). These socks have a mesh size of 100 microns, allowing them to trap even the smallest particles and debris.

Easy Installation and Maintenance. Rinse before use. Fit Seachem Filter Sock into any standard sump or overflow system made for collared filter socks. Remove as necessary for cleaning. Under normal use, cleaning can be accomplished by simply rinsing with a high-pressure hose. For more aggressive cleaning, soak in 1:10 solution of bleach and water for 24 hours and then rinse thoroughly with a high-pressure hose. It can also be cleaned in a standard clothes washing machine; wash on a moderate setting with a cup of bleach added to the wash cycle. Once the normal rinse cycle is complete, Seachem Filter Sock is ready for use.
