That much light you better have CO2 Injection and Tons of plants, and a killer fert regime. other wise all that is going to grow is algae.

Mount the lights atleast 12-16" above the tank at minimum to reduce the lgith intensity. Keep the lighting short with the MH only a few hour and run the CF or T5 more.

That is the only thing I cna think of. You will still probably have some algae aswell. but may keep it to a minimum
