Your bioload may be high with all those fish. I'm sure the tang police will chime in.

looks like nothing in your tank really requires high light except your acros so light might be a problem. You need to post parameters as SPS and i think ESPECIALLY acros are very sensitive about stability.

ok this is my parameters:

s.g. 1.023 ph 7.9 NH4 0 no3 2.5 ppm ca 420 kh 3.8 meq/l
mg 1400 ppm , every week Strontium 10 ml ioden 5 ml

my tank size 250 L

looks like a lot of softies in there. If you dont do regular water changes or run carbon they will start to have chemical warfare and kill off the hard corals. And as was said before could be fish load.
