Help with Umbrella Leather

[molybdenumman]

Whas'up

Ever since I moved to my 90 gallon tank in mid December, my Umbrella leather has not been itself. The tentacles are retracted for 1-2 weeks at a time. Every so often it will shed a mucus coat and the tentacles will emerge for a day or so.

It is being exposed to more light now (330W vs 220W PC). It is about halfway up my tank. There is lots of flow within the tank. All parameters seem to be fine.

Ca 370 ppm
alk 4.3 mEq/L
pH 8.1


Has anyone had this happen? Is the coral sick / dying? What can I do?
