Why can't I keep some corals alive? Acros, Millies, Birdsnest, Monti Caps, Gonis, Galaxea...can't keep them alive. Zoas, Acans, Hammers, Favia...all fine. Light is set correctly with each coral placed under the correct PAR. Water tests are as follows:
Calcium - 434
Alk - 9.3
Magnesium - 1270
PH - 8.3
Nitrate - 12.1
Phosphate - .21
Salinity - 1.025
What am I missing here?
