Just want to post some observation after about two months of use of this staff in my canister filter. I also have a liverock rabble in lower chamber.

I did water change today and cleaned the canister to.
Rock rabble is absolutely covered in all types of sponges(I am saying hundreds), so is the outside and inside of the basket. Everything in a tank been growing like mad. Don't know for sure if I would relay this to Chemi-pure or not. I don't use carbon or any other media.
