Where to get Lugol's locally

[Samw]

Ok, my Acros continue to decline 1 colony after another. I think this all started because I overdosed on Chemiclean. I've done some water changes and will do more. I have added chemipure. I've increased the power level of my skimmers' airpump to add more skimming. I've already lost some nice colonies and frags and a few more are starting to go. I would like to try dipping them in Lugol's next.
