Elegance Coral lighting vs. Ca/Alk/Mg

[dragoneggs]

Just wondering about other owner's experience wth Elegance coral? I have an elegance coral that went from Halides to LED and I started it at bottom and after a bit it seemed to be receeding, shedding its guts and losing its color to almost milk. I first moved it up for more light and after no change (in fact getting worse) I moved it to 'shade' and the bottom of the tank (24in) and it seems to be recovering. I thought it was a goner!

I thought that going from halide to LED would be no problem but I am starting to wonder if the spectrum change is giving them too much of a 'boost'. Water quality has been excellent except I have raised my Mg and Alk to be better in line with my Ca. That definitely promoted the purple/grey corraline algae as well! Look forward to any owner comments on this animal.
