Review on Seachem Purigen Organic Ultimate Filtration Resin 100ml (3 Pack) - Top Choice for Pet Faves - Aquarium Fish Tank Filter Media for Freshwater & Saltwater - Bonus Water Test Strips Included by Brando Carpenter

I have used Purigen before and it has worked great. I also received some of these that appeared to have been used previously and sent tiny pieces into the tank even though I put the package in the extra media pouch. I was hoping to have ordered from the right seller this time, but no. When I took it out of the box, it was damp and stains fell on my hand. I tried to flush and just got a lot of stains. I won't put it in my tank. Don't buy this.
