btw how much iodine are we talkin here? couple drops per gallon?
Try to look for Povidone (it's iodine, but less harsh/easier on corals). Most drug stores sell a store brand of it. I usually drip acclimate the corals to the tank water and then dose the bucket. I start with 1/2 teaspoon iodine for 1 gallon. Some iodines, such as Tincture come with a dropper. The most often recommended dosage is 20 drops per 1/2 - 3/4 gallon. You can usually buy a little eye dropper from the pharmacy if you like the droplet method of measuring better. Honestly, I do not do exact measurements anymore, it's really a guesstimate. As for Melafix, usually even places like ***** carry it in the fish section.
