Seachem Filter Sock Large
Filter socks are a critical component in maintaining water quality in aquariums. They remove suspended debris and detritus, which often lead to excess dissolved organics, nitrate, and phosphate when left unchecked. This makes Seachem Filter Socks 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.

I’ve used these filter socks in my 120-gallon sump for over a year. The debris removal is excellent, and the welded seams haven’t failed. Water clarity has improved noticeably. Easy to install with the plastic collar.

Great quality. The 100-micron filter catches fine particles that other socks miss. No fiber shedding after months of use. Fits perfectly with my overflow system.

Works well in my reef tank. The plastic collar makes installation quick. A bit on the thick side, but it holds up well under daily flow.
