Are you sure it is 18 inches deep? This seems rather deep for a 29 gallon tank. If it is that deep you may need to add another 65 watt bulb to the tank.
If it is 16 inches
I would think you could keep most soft coral and LPS. I would not try to keep any clams or Acroporas. Also, if you use a 50/50 as one of your bulbs and a 10K in the other you will have more usable light for photosynthesis.
