I would like to make a stock solution of Zinc as well as an Iodine supplement to add to my system. I had a Triton test done and found that it is low on iodine and zinc. I tried using the Triton supplements twice but cannot afford to continue dosing using their extremely high priced additives. I need to come up with an alternative. Does anyone have a recipe or calculator for making stock solutions of these? I was thinking that using a lugol's Iodine solution may much more affordable way to go although, I cannot find anything for Zinc.
