Sorry to jump in so late but PC lighgint is not enough to keep this coral alive and happy. You may be able to keep it alive, but it will loose it color and brown out, with slow to 0 growth. Most SPS need T5s or MHs to meet their high demand lighting requrements. Don't go by watts/gallon as that is garbage. The light spectrum that PC bulbs give out are not able to supply the coral with what it needs.
I'd treat it for the redbugs, upgrade your lighting - or find it a new home.
