Yes, especially if you go with pendants. I'd be really tempted to go with two bulbs over a 36" tank though.
IMO, you'll be fine with a 2x96w
PC system though. 12" is pretty shallow and the
PC's should penetrate that depth quite well. What kind of corals do you intend to keep? That is what will really determine the lighting you need. If you are going to want lots of
SPS in this tank, then I'd say go with the halides. Otherwise, the
PC's should do the trick.
