I have a 120 mixed reef tank!! I feed my LPS, SPS AND SOFT CORALS - BRS Reef Chili and my Dr G's Photoplankton ON M-W-F ONLY and my sps and lps corals were doing great. Then I started adding REDSea Reef Energy A ( Carbs Nutrition) and Reef Energy B (Aminovit).. - 5MLS EVERY OTHER DAY....Ever since i started using these two products I have lost two SPS corals... Also, I dose 25mls of Alk, Cal and MAG every day through my Eshopps doser and that is it.. I do a weekly water change of 10 gallons every week. Would love to hear your thoughts on what to do. This is what one looks like yesterday until I took it out and tossed in the garbage.. Thank god this pcs below and one other pcs thats a birdnest sps that's dying on me.

I dose 15ml of Red Sea A and B into my 90 gallon every other day and everything looks great... Issue might be your 0 nitrates? What happened after you stopped dosing the Red Sea stuff?
