Filter Sock 100 micron welded

Seachem Filter Sock – 100 Micron (Welded)

Filter socks are a critical part of maintaining excellent water quality in marine and reef aquariums. By trapping suspended debris and detritus before it breaks down, they help reduce excess dissolved organics, nitrate, and phosphate—keeping your system cleaner and more stable.

Seachem 100 micron Filter Socks are designed for durability and performance. Featuring strong welded seams (not stitched), they won’t fray or break down over time, even with regular cleaning. The singed finish reduces wear and prevents loose fibres from entering the water column, making them safe for sensitive reef systems.

A 100 micron rating provides excellent mechanical filtration without clogging excessively, while the rigid plastic collar ensures quick, hassle-free installation and compatibility with standard sump and overflow fittings.
