The Bag is an innovative welded filter bag with a durable non-stitched seam. It has a 180 micron mesh, is resistant to bleach, caustics, and acids, and comes with a convenient resealable locking closure. It is available in a convenient 5" x 10" size. It is ideal for all filtration products and has an exceptionally long life.
Seachem manufactures aquatic plant fertilisers and water conditioners. Aquascapers and planted tank enthusiasts will benefit from Seachem's innovative products, as they can draw upon a vast range of helping agents. Especially mentionable: Seachem Purigen, which makes the water in an aquascape crystal-clear.
The bag is very fine, and made from a quite hard plastic, so it isnt very flexible. The bag is very sturdy and mesh is fine, so there is no way purigen will get through the mesh. (read more)
The bag is very fine, and made from a quite hard plastic, so it isnt very flexible. The bag is very sturdy and mesh is fine, so there is no way purigen will get through the mesh. However, the closing mechanism is a zip tie that can be used to tighten one end of the bag. I bought this bag because my previous bag (different product) leaked from the opening. It seems like it will hold (and it has so far), but I am a bit sceptical. Purigen leaks look horrible. Instead I recommend buying the 100ml sealed bags of purigen instead. They will definitely not leak.
