Just make sure you don't overdo the light, or you will have a tank of algae.
On this tank, a single tube T8 will work fine. The tank is 30 inches long, so a tube that is 24 inches will probably be what you can find. A 30-inch tube is possible, if you can get a fixture. Another alternative is an incandescant fixture (screw-in bulbs rather than tubes), with 2 or 3 sockets. The CFL bulbs in 10w (three of them) would work.
Whuiloe shop lights are fine, they tend to be better over standard 4-foot tanks. You may or maynot find them in 30 inches (fixture). My local Petsmart carries fixtures without the complete hood; I've no idea how much they are, but I have seen them. You want T8 (regular fluorescent), not T5, so be careful on this, as many aquarium fixtures are T5.
And I agree on the nutrients/yellow leaf issue. Flourish Comprehensive Supplement liquid will work fine.
