I think the most intelligent rule I've heard concerning aquariums so far has been that you shouldn't add trace elements that you don't test for. Well, I've heard that soft corals thrive with additions of iodine, but I have yet to see a test for iodine. Am I just unlucky in my search to find one, or do they not exist?
