You probably have 24" bulbs at 20W a piece over the tank... (a 29 is one of those odd tank sizes which doesn't have a corresponding bulb length). 2 years is much to old for anything except fish. Normal fluorescents last 6 months, while CF
can last to 12 months on a good ballast. Look into a 2-4x65 CF
fixture, they may even make one for a 30" tank.
Without knowing a rough figure of LR
its hard to say if it is enough filtration. How much does it "fill the tank"?
5ppm nitrates isn't bad at all
A skimmer is always a good thing.
Occel and Percula clowns are rather hardy.
