Platygyra coloration

[kevinathom]

Just curious to see if anyone has thoughts on why platygyras may lose color. I have one where the "valleys" changed from brilliant green to black. Chems are stable, and it is mid-tank with moderate flow. It seems healthy, but just black. Attached is a picture from when I first bought the frag and another pic from today.

Is this a led lit tank? If so the problem is the spectrum in which it receives.

I'm running DD T5's. The bulbs were 12 months old when I replaced them in
February.

What bulbs are you using?

I'm running an aquaticlife 4 bulb fixture geisemman bulbs: 2 actinic+ bulbs for 10 hours/ day, an aquatic coral and a super actinic for 3 of those hours.
