Use it w/ success too
I have used Kick Ich a few times in my reef, and always try to keep a bottle around just in case. I have all kinds of inverts, and this is the only thing that I can safely add without doing major disruption to the tank. I don't have a hospital tank, nor can I remove everything out to treat. I have never lost a fish to ick, and the tank will be 3 yrs. old on Feb. 13th. Some may call Kick Ich a snake oil - whatever. But I won't go without having a bottle around, esp. with a Regal Tang that I have. The corals or inverts never have probs. w/ the Kick Ich, either. You need to remove your carbon, follow the directions carefully, and if you need to dose for 2 weeks, then do it. Also, depending on the size of your tank, you might need more than 1 bottle. I'd rather spend $20-30 on this than losing my $20-50+ fishes one by one.... 8O
