I would say for now, without anything in there, yes. But once you begin stocking up corals, no. Definitely would not be enough. You might get away with some softies, not even all of them. It's just not enough light, and T8 bulbs are nothing compared to T5's or VHO's. Not to mention that it's only an 18" fixture. If you had a larger one that covered more of the tank then maybe you could do softies.
