Ok so I have a mixed reef. Everytime I put sps in my tank within a week they go downhill. Par is 200-350 on these parts. I can put anywhere and it'll be the same outcome. I have my flow and everything else good. Lps doing great and all. I think it's something hidden so I'm going to do ICP test. My last test for my last tank I did see I had low to none iodine and I had the same issue in my last tank even with all parameters and flow being good. Will this be a issue for sps. They start to lose flesh and don't do well within days like I said this is only a sps issue nothing else. This goes from the hardier Montis to everything else even birds nest.
