So..in the end I now believe that my ONLY problem was that my bulbs were old. Everything else was a spin off effect from there. At this point, I believe the corals are healing. Unfortunately, some have suffered such damage that it will probably take months to recover completely. I probably lost 2 or 3 corals completely.

That's an important observation made possible by the little PAR meter. I'm glad that the time/money/effort that went into its purchase has paid off for someone in a tangible way.
