Right, Quick-Cure is great for clearing Ick. I would use it in conjunction with higher temps and the best water conditions you can achieve.
Just a thought on Ick med's:
I haven't had nearly as much luck with Aquari-Sol as I have with quICK-Cure. The only bummer about the latter is that, as others have said, it stains the sealant in your tank. To me, this is a small price to pay for the well-being of your fishes! Good luck, hope all turns out well
