did this start with the new lights.Some acros require time to adjust to new lights..I have had this happen to me with 3 acros when I changed a bulb.I used reef dip wich helped and then placed the corals lower in the tank.Reef dip from seachem does help you can dip the coral more than once.I also used it when adding new corals
