Filter Sock 200 micron welded 17.5 x 40.5cm

Filter socks are an essential component in maintaining water quality in aquariums. They remove suspended debris and decomposed organic materials, which often lead to increased dissolved organic matter, nitrates, and phosphates when left unchecked. This makes Seachem filter socks an indispensable addition to any pump or overflow system.
