Howdy all I noticed white patches on my new Monti frag, is this the work of Nudibranchs, light bleaching, or iodine deficiency? I've got Iodine to dose but it isn't formulated for nano tanks, and I don't have a means of testing for Iodine. So I'm not really sure what to do, I've already moved it to lower light. Should I dip, try and dose, or observe how it does in its new location. Any info or help is greatly appreciated. P.S. I've also been dosing with Kent Marine Nano Reef but have no clue if it contains Iodine or not
