I stopped the treatment, I did a 50% water change, did a very thorough deep gravel vac, and removed some hollow ornaments to dry out. The fish already look very happy! Its been about 4 days with no signs of ick, I would have liked to go for a full week but the fish looked very stressed. I'm going to hope for the best, let the temperature drop in the tank and hopefully slow down any remaining ick parasites and continue with vacuuming the gravel for the next couple days.
