its not just your fish everything in that tank is dying, corals are closed,fragplugs are bare and a clear nutrient problem happeneing.
honestly if you want some help your going to have to include equipment list, schedules, parameters(in full) and livestock....without its just a shot in the dark and my shot is no oxygen i see 3 powerheads none of which are breaking the surface....your green star polyp has no movement at all and all fish are hiding,its also something they dont test for at lfs. how long did you mix the salt for and how did you go about mixing it and adding it to your system??
