Where to get Lugol's locally

[Samw]

Brad. I haven't measured Alk lately but it should be fine. I'll test again and let you know. I've been losing acros and pink bird's nest. I think it started happening after I started using Chemiclean for Cyno. For sure, my purple acro turned brown the day after. Also, my skimmers clogged up and although they provide a bit of aeration, there wasn't enough bubbles to create skimmate for about 2 months now. That was my fault as I was just being too lazy to clean the airstones. After seeing my low night-time DO levels, I've changed the airstone in one skimmer and cranked up my air pump. I see skimmate forming once again. I should hopefully see some improvement in night-time DO.

trilinearmipmap, that's the 2nd suggestion for pharmacy. I didn't realize that they would have it as well. Is it the same stuff that people use to dip corals?
