IMHO I would keep the schedule you have posted for everything, except the MH. My suggestion would be for the first week, only to have them on for an hour, and increase inclemently each week. This is just to get the corals use to the increase in light over a period of time. Also watch for temp changes in your water, that will be a good indication in your lighting period for the MH, or might need to explore a chiller, or just raise the light up a bit. Also with the lighting change, you want to make sure you don't get a an algae outbreak. Again that is just my 2 cents worth, I am sure there will be others to chime in.
