My point is, there is always the off chance that you will have a fish that has a reaction to the iodine. Just like people, fish can have allergies. Granted, iodine is a rare one, but I have that particular problem myself, as well as niacin and potassium sensitivity....(me, not the fish...)
I try to avoid any chemicals in my tank that are unneccessary, and that includes iodine. Besides, rock salt is almost as cheap as morton's, so in my mind, it's not a big deal to go ahead and have something that is darn near guaranteed not to kill my fish on the rare instance that I would have a sensitive fish...
Just my opinion...
