I had a lot of coraline die off as well. I did 3 ICP tests during the vibrant dosing and I can tell you that even though I was dosing the Red Sea trace elements program based off calc demand, my results showed undetectable amounts of iodine and iron. Potassium was very low as well. I did stop dosing the vibrant and dosed a lot more iodine, iron, and potassium to get the levels to the recommend parameters. I didn’t lose a coral after that. Iodine for sure helps no matter what. I think a lot of the coral meds and in tank treatments contain a fair amount of iodine. But I could be wrong.
