What is your photoperiod?

My tank is 240G.
I run my Atanic VHOS form 11am to 9pm.
I only run my MH for 4 hours from 2pm to 6pm.

I run my Powerbrites from Noon to 10pm and my 150w Halide from 3pm-9pm. I'm playing with my lighting still. Seeing what works best. The Powerbrites are set back a bit not directly on all the corals so they get some light but not the direct power.
