You'll likely need to use CO2 and ferts with the FugeRay if you don't raise the fixture or use a material to dampen the amount of light output.
I know that the Fluval Edge 6" is slightly shallower than the Spec V, but at 12 or so inches, the Fugeray 16" puts out 30 PAR.
Would 30 PAR require CO2 and dedicated fert regime?
