WECOClassic Filter Media Bags Fine Mesh Drawstring, 8" X 12"

It works with Purigen. I give it 5 stars. The price is ridiculous. I give it 0 stars. Average 3 star. When simple mesh bags sell for more than twice my crystal clad stockings, its Cray Cray. Yet, im forced to buy them because I love my fish.

I bought this to use with purigen and it is absolutely perfect for that use. I have a 5 gallon tank with a hob filter and it allows me to use appropriate amounts of it as needed for a smaller setup. Shipped fast too!
