I love this stuff. I have it in my shrimp tanks that have Matten filters. I was given a small start of it from a member of Simply...same guy who gave me my first very red shrimp. It took ever to reproduce in the office red shrimp tank before I could steal some from it to put in my 2 shrimp tanks in the fish room. Now I have mountains of the stuff. I've recently found out that it's great for tiny baby snots to feel comfortable in as well. It gets sucked up during WC in my tanks with sponges.
