1 tube of any sort will NOT be enough light to grow anything. Let alone SPS corals. These single light fixtures are OK for fish only tanks, and pretty much useless for anything else UNLESS what you are trying to grow is in less than 4 inches of water and directly below the tube (pretty useless in other words). Then you might be able to get away with some types of macros and a few zoas, but nothing else.

I would look into getting at least 4 T5HO tubes above your tank if you plan on growing corals and whatnot. That should be enough light for macros, soft corals, and some types of low light LPS. If you want more, I suggest that you look into metal halides... they are more efficient, produce more PAR, and you'll love the shimmer effect from the water's surface.

Hope things are going well, can't wait for the FTS!
