Digitata turning white question

[merfury1989]

Hi, why is my digitata turning white, I recently noticed it.
In terms of placement its at the top at direct light and direct flow.
Other SPS doing fine (such as Birdnest, Stylo), all share direct light and direct flow.

Could be a laundry list of things. Too much light, too much flow, pests, nutrients, etc.
Montis are pretty hardy, but I suggest moderate flow and light.

Might want to tell everyone what your parameter’s, PAR, RO/DI TDS, and some general info about your tank over the last couple of months. Also, is the tissue dropping off or just tuning white (if there are still polyps there or not).
