what lighting should I get

[kwirky]

I second the tek lights for your tank. It's not very long, front to back, thus making metal halide an inefficient choice. With HO T5's you'll also be able to fine tune your colour and brightness with bulb choice and location. Stay away from power compact. It may be cheaper to start up but the bulb replacement will bite you in the rear.

If you go with T5, make sure it's a system that has individual reflectors for each bulb.
