I had a 29 with a hood I made from parts at ah supply; 2X55W. You couldn't cram 4 55W tubes in their hood, but you could get the light/reflector kit and build your own hood. I kept a mixed assortment of lps/sps corals in my tank with 2 tubes, so I'm sure you'd have the light. Actually, if it were me, I'd consider 3 tubes, 1 blue, 2 white. (You can get supposedly 03 actinic PC tubes from hellolights) 4 tubes under a 12" tank = 3"/tube space front to back. This leaves no room for reflectors.

Check out ah supply; you'll get some ideas at least.
