I have PC's and MH over my reef, and I keep the PC's on 12hrs and the MH's 10hrs- I also have LED moons running opposite the PC's...

Hope this helps,

If you just installed that new 250W, I would only run 4-5 hours. your corals may not like you very much. I always cut my photoperiod when I install new bulbs.
