Do you have any pics of these corals in question? with out seeing them i would take a far out there guess that it may be due to lack of flow and sediment build up or lack of light.....with out seeing them i could be way off just a guess.

Just keep water quality high and whene you feed turn the skimmer off for a few hours.

Bleaching or RFD? Rapid Flesh Deterioration, thats not good... you might only walk away with a frag you could save.
