Seachem – Filter sock – 200micron – 7in. x16in.

Seachem Filter Socks are an integral addition to any sump and overflow system. In addition to a 100 micron rating for exceptional particulate removal, they feature welded seams, which, unlike threaded seams of similar products, will not breakdown over time. They have a singed finish, which reduces wear and prevents release of fibers back into the water column. Finally, the plastic collar simplifies installation and easily fits standard sump fittings.
