I'm sorry, it was below at the time. My bad. It moves.
So, I'll give you my response here since I steered you in the wrong direction previously.
I have only PC lighting on my tank.
I work it for a total of 12 on and 12 off.
My actinic PCs come on an hour before, and stay on an hour after my 10Ks.
My 10ks stay on for 10 hours in between that.
My corals seem to like it this way. I haven't seen any recession or anything. It may vary a little as the light bulbs go bad after about roughly a year. But, the bulbs should be replaced then instean of changing the light regimen.
