Recently my Triton came back with a 0 in iodine. I have never dosed iodine and have read mixed results about doing so.
However, I have an orange Montipora that is starting to go white. It's been in my tank for 5 months and hasn't shown any adverse effects from my lights (Kessil 360's at 70%) or water quality. So I'm thinking maybe it's because of the lack of iodine.
Water quality as of yesterday
1.025
11.3 dKH
414 ppm CA
1460 ppm Mg
18 ppm Nitrate
With that said, any recommendations on the right type of iodine supplement and test kit for that type of supplement. I understand you need to test for the right type of iodine your dosing so want to make sure I get the right two together.
My Triton test came back with low iodine as well. I went with their recommendation and bought their Iodine. We diluted the Iodine with RODI (10:1) and we dose 3.2ml a day. Our tank is ~225g and we're seen great health and growth with our corals.
