minimum required lighting period

[christyf5]

Hey guys,
I had another rough bout with the algae tonight. It almost finished me off. I was just wondering what the minimum time for my metal halides to be on to keep the corals happy in the hopes of slowing it down. I'm going to leave the actinics on 10-12 hrs/day or should they be reduced as well??

TIA
