so yesterday i got a new acropora frag from my lfs
. It look healthy but not happy in their frag tank(meaning its polyps were just barely out. I have fluval 48 leds so i put it in the upper region of my tank. Within a few hours one of the tips turned white. Today it is still white hasn't gotten worse. Could it be from stress of a new tank, alk
burn(i dont have an alk
test but people say it could happen from quick changes in alk
) or is it bleaching? What are your thoughts, thanks.
