I just upgraded to MH a week ago..I acclimated by putting several layers on window screen over the tank and removing one every other day. Now my acropora staghorn (which had been brown) is turning green but there are pinpoint areas of white which are either bleaching or receding?? I'm not sure..unless growth shows up like this? It's almost like the outer 'skin' is split in one tiny area. What should I do??
