Just a piece of advise, I had Ich on a couple of fish and decided to use Kick Ich, which was supposed to be reef safe, and it did not cure any of the Ich. In fact, it spiked other elements in my tank and I have lost the new fish along with some that have been in the tank for a couple of years. I feel that my tank is in worse shape now than what it was before I used Kick Ich.
