have a 75 gallon, 7 animals, 90lbs of LR. have recently been working to get more corals. Tank is going is going on 2 years old and I had not been adding any coral supplement, like calcium and Iodine. Is it O.K. to add Iodine once a week. In the last 3 weeks I have added Iodine and my corals to seem to be looking better. I just do not want to over do the iodine.
