290G Peninsula Tank

Thanks, sadly its not really looking good. Sitting at about 80% Sps loss right now...just can't figure out what is wrong. Watching all parameters and they are normal. PO4 is a little high at (.06) Checked equipment for failures....replaced some just for the heck of it. Changed GFO and changed carbon brands just in case. Scrubbed my water change station down completely. Changed Di and prefilter on rodi.
Last resort has been doing 100G water changes every day...trying to change something for the positive.

Fish are happy but dead corals bring algae and cyano. I can't remove them fast enough.

Corals develop large white 'spots' and then return in all directions from each spot with a few days.
