I don't know for sure, but I wouldn't think iodine in the concentrations we're talking about here would even make ich blink. If it did, it'd be a recommended treatment, I'm thinking. I'm sure at some concentration it'd kill it off, but I'm sure at that point it'd kill everything else off too.
Regarding the drip acclimation temp drop question... as Sadielynn mentioned, if you dump out half the water in your bucket once you've doubled the original amount, your temp shouldn't drop too much. I vary my drip rate a little depending on how much water I start with and how different the LFS
water is compared to my tank. I basically try to double the water volume in the bucket every 30 minutes.
