your corals will probably be fine with about 8hrs of halides. anything more that that is mostly for your benefit not theirs. also, the longer you run your lights the more algae you will grow and the more electricity you will end up using.

Much too many hours of MH lighting. I'd recommend (opinions vary) T5's for 8 hrs. and MH's for 6 hrs.

I can't tell you when to have the lights cycle on and off because that is a very personal preference. Most people like to have the lights go on when they are home. I don't see a purpose in having the lights on while you're at work or school and then turn off when you get home. When would you get to enjoy the tank?

In summary:

T5's go on at 'zero hour'
MH's go on at 'zero +1 hr'
MH's go off at 'zero +7 hrs'
T5's go off at 'zero + 8 hrs'
moonlights go on at 'zero + 8 hrs'
moonlights go off at 'zero + 10 hrs'

Hope this helped

i try to mimic the natural day out on the reef where these corals are collected. algae should not grow in your tank if your nutrient levels are low, no matter how much or what color temp the light is.
