Run just the one light and make sure you are on top of the diy co2 and ferts. After you upgrade to pressurized which will be more stable/consistent run both on a "noon burst" schedule.
I am running 2x96w on my 30g and as long as the co2 is running and ferts are on schedule I have zero algae problems and the plants look amazing!
