montastrea dying, i think

[derekman]

My montastrea is losing tissue between the polyps, and the centers don't look good on one side either. I have SPS, plate, derasa clam, mushrooms and frogspawn, all of which are doing great in my tank.

salinity 1.023
ca 420
NH4 O
n02 O
N03 <10
DKH 8ish
PO4 acceptable (salifert) (i'm typing from work, can't remember number)

72gal bowfront
feed DT oyster eggs bidaily
tunze 6100 &2 MJ 1200 flows
390 watts of PC and sunpod 150w HQI

I read they need a lot of light so I put it under the HQI at the bottom of the tank. Do you think maybe the flow I have in the tank, is too high for this particular specimen? is there anything I can do to prevent the final melting stage of tissue necrosis? Is it a goner?

from experience montastreas don't need much light at all, I'd try placing it in the shade and seeing if it survives, do you have any pics?

Mine bleached pretty badly before I placed it in the shade.
It colored up back but took a while.
