So over the last month I have seen almost all my zoa colonies close up and begin to melt away, they refuse to open up and seem to be dying off, any insight on what is going on? Parameters below.
salinity: 35
Temp: 78.5
PH: 8.1
Orp:330
Alk: 9.4
Cal: 465
Mag: 1480
Phos: 0.04
Nitrate: 9.8
Tank is about 10 months old, and all parameters are very stable and do not fluctuate.
