Seachem The Bag – Premium Welded Filter Media Bag (13 x 25.5 cm)

Seachem The Bag is an innovative, high-quality filter media bag made from durable polyethylene mesh with welded seams. Unlike stitched bags, The Bag is resistant to degradation from bleach, acids, and caustics—making it ideal for regenerable filter media like Seachem Purigen, Matrix, and PhosGuard.

Its 180-micron mesh is fine enough to hold even the smallest resins while allowing optimal water flow. The resealable locking closure ensures secure containment and easy reuse. The Bag is suitable for use in canister filters, sumps, hang-on-back filters, and internal chambers.
