The best, and maybe the last, aquarium filter media bag you'll ever buy. The 180 micron bag features a resealable locking closure and durable, non-stitched, welded seams for easy, long-lasting use. Simply place desired chemical filter media such as Seachem Purigen and close The Bag using the resealable locking closure. For best results, make sure aquarium water flows through the filled media bag.
The Bag is chemically inert and resistant to bleach, caustics, acids or other harsh environmental exposure likely to take place during regeneration of filter media. 180 micron interlocking mesh holds even the finest resin media. 5" x 10" size.
