I would agree with trill. I ran the exact same set up on a heavily planted tank for a year (4X96W 10,000K PC's / no CO2) and had some limited problems with algae etc... but the growth rate and "lushness was not what I expected. I eventually reduced it to 2X96W 10,000K. with less algae issues but really felt that CO2 dosing was what was missing.
