I recently moved my tank from one room of my house to another. All of the corals did fine except one colony of purple montipora digitata. Ironically I have two colonies, one larger and one smaller frag that was originally a part of the larger colony. Ever since the move the larger colony browned out whereas the smaller one stayed purple.
I recently changed lights. I was running a reef capable led
with an extra 24" strip of 1 watt actinic lighting (innovative marine Skkye strip). I recently changed my lighting to an Ocean Revive Arctic S026 led
light which is a much more powerful full spectrum fixture.
I have noticed in just over 3 days that the smaller monti is looking even more purple than before whereas the larger looks the same.
What are the chances that the color comes back to the larger colony? How long does it usually take if it is happy and receiving the light it needs?
