I have the same size tank, using it as a home for a peacock mantis and a damsel. I'm not very happy with it, to be honest. The filtration isn't adequate to keep the water "sparkling" like I'd prefer. If your tank will be FOWLR, the lighting will be fine, you might even be able to keep a few very low-light mushrooms. One of the ballasts in my hood blew a long while ago, supposedly it can't be fixed w/o getting a whole new hood! The single bulb is fine for my mantis and the coralline algae has survived in spite of the low light. There were a few polyps on the rocks, but they died off. A couple of mushrooms are still hanging in there, but they're not growing. If you ever think you'll want to keep corals, you may want to look into getting a pc retro kit for the hood.
