Platygyra/Maze Coral browning

[meverha1]

Fairly new (purchased Black Friday) green/white Platygyra frag has started to brown a bit along it's green ridges.


Tank: 110 gallon tall (30 inches deep)
Params are normal
Lighting: 2 Radion G4 Pros using the LPS Growth program at 65% power.
Placement: Bottom of tank, sand bed.

Like I said, the frag seems to be browning on it's ridges. I feed twice a week but really haven't seen a feeding response (sweepers) since the first time I fed it. Although I do think it's eating.

Is it possible that it's not getting enough light? Any other possibilities?

What exactly are your parameters? Do you have any other corals in the tank? How do they look?

When I checked them on Sunday they were "normal." My Alk is always a little high but it's steady - it hasn't changed in months.

Plenty of other corals in the tank and everything looks good except for this one and one tiny frag of Zoas that refuse to open no matter where I put them.

Acans, Trumpets, Frogspawn, etc... are all thriving.
