Im hooking mine up in a few minutes,. My LFS says it is AWESOME to have this. They say it does kill ich, you also wont have any algea problems anymore. It's really expensive, but hopefully worth it. My hippo is now COVERED in ich. She is in my qt,. I treated with copper. She's so covered in it, it looks horable, BUT she eats still like a champ, so thats a good sign.
