Montipora bleaching

[Steve S]

Nubie to caring for a montipora. I’ve had some good growth, but have noticed bleaching in the center area of the coral. I still show white tips but the center bleaching has me concerned. Any advice?

Any pictures? Could be in a too intense spot of lighting. What are your PMs?

Here it is...moved to the bottom of the tank (cube 40) Kessil A360W tuna blue at 55% on color and 50% intensity through a Kessil X controller.

How long has it been in that spot? Any corals close by (Chemical Warfare)? Also what are your PM's

My encrusting monti bleached twice - once when I got new lights, and once when PO4 and nitrates got too high. Check those and post the results.

Are pests a possibility?

I moved it about a week ago, prior it was up approximately half way, I thought it might be getting too much light. I don’t have any way of measuring par, nitrates close to none.

No other corals close by
