I've had the scoly and fungia for about 6 months and recently it started to recede. The plate coral receded earlier made a comeback but started to die off again. I think it's due to high flow and direct lighting? I move the scoly into a shaded area but I know the flow in that spot is high but nothing crazy. I included the tank parameters below, I've been trying to dial in my dosing with all for reef and kalkwasser over the past two months with testing of course, and things seem to be stable even though Ca is low and Mg is high.
Parameters:
Alk 9.3
Ca 350
Mg 1550
NO3 25
PO4 0.03
