Honestly, I expect that the problem is not the pH. A lot of Tanks of the month have run in that general range, around 7.8. Phosphate at 0.1 ppm is high enough that it might cause problems. Personally, I'd start there, and possibly check the feeding and lighting. Did the corals do well for a while in the tank? What kind of lighting does the tank have? LED doesn't seem to fade over time, but bulbs do.
