I had no luck with Kick Ick in my display tank and fish had ick about 10 days into treatment. At the outset of treatment, I even increased the dosage slightly and dosed 3 days apart. No skimmer on that tank, only PHs. Another local reefer used it in her reef and her fish continued to have ick during treatment.
Here is a RC thread from 1999 on Kick Ick:

The manufacturer wrote extensively about his product on the thread, which is why I tried it. However, ime, it was a waste of $50
I'd like to hear about your experience with Kick Ick once you've tried it, though. If you could keep a log of how much you dose, when you dose, if you continue to use your skimmer, etc. the shared experience will be helpful to others when deciding to use Kick Ick.
