There is no reason to add iodine into our tanks. The artificial salt, in addition to the foods we feed our critters with, are high on iodine. Majority of our tanks have iodine level that is higher than that of NSW. Don't believe me, read the following article by Ron Shimek.

Beside, iodine helps shrimps molt is a misunderstanding. Iodine is toxic to shrimps. They molt in order to get rid of excess iodine in their bodies, among other functions.
