sun corals

[dfreeman]

I thought sun corals were not bothered by light. Went from pc to 250Mh and corals not happy. dont open up like they were. my tank is 30 deep and they are on bottom. Been 2 weeks now, not enough time yet or does the light bother them after all. All water parameters are stable. No new additions or changes accept lighting.

sun corals preffer shade, so find a nice shady spot and see if that helps.
