I am assuming you mean coral wiseÉ I have kept SPS under PC before but they went brown right away. Funny thing was though they stopped growing vertical and started putting out a massive base.
I find LPS do awesome under PC. I have a Blasto Merleti that has been under PC for 6 weeks and now has 6 new full heads and is sprouting another 8 small ones. My Wellsi that was dying under my MH has done a 180 scince being in there and has come back 100%.
I am thinking of building a AIO 25 gallon LPS Zoanthid tank and after seeing the results with this little nano of mine I am probably going to go PC.
