I thought you had 2 vho's as well as 2 metal halides to put on?
If that is the case just start out with a few hours a day of light and then slowly increase the time the lights are on. If you see bleaching then your coral has not acclimated to the new light as quick as you are increasing it.
It will be more of an obversation that helps you add more time to the length the lights are on. So in a week or 2 you should be able to go all day without any issues.
The heat issue is if your starting out metal halides for the first time they can increase your water temp more than other lighting so you just want to make sure you monitor that as well.
