Do you think the Ray II at just 12" above the substrate (for the Fluval Spec v) will push light levels high enough to demand CO2 and regular ferts?

I'm aiming for a happy medium where growth isn't explosive, CO2 isn't required (but perhaps liquid CO2 can help) and where I don't have fert every day.

I'm wondering whether the Fugeray or Ray II is more appropriate for that at the 12" height.

Your thoughts?
