Can't raise alkalinity enough?

I would also make sure that you test for magnesium as that can throw your calcium/alk balance off. I agree that yours isn't too bad and would not be too worried about but magnesium is important to test for to maintain balance.
I have my cabbage coral fairly high up in the tank under MH light (not directly) and it does very well so you may want to think about moving it up.
