Default Lighting on 40 long

I have a 48" 4-bulb Tek T5HO fixture from an old saltwater setup. I want to use it on a 40 long -- 48"l x 12"w x 16"d. I'd also like to keep plants that require "medium" light, and would like to avoid CO2 (which I understand can be done with PAR = 35-50). If I used only one 54W 6500k bulb in this fixture would that still be too much PAR to avoid using CO2? I saw the sticky thread on lights/PAR, and if the Tek calculated values can be taken at face value it looks like the PAR might be about right near the bottom of the tank, but might be closer to 75-80 at the surface of the water.

Anyone successfully running a setup with one bulb 54w T5HO bulb, or have any advice for me?
