20 gallon long light advice

[daboyprince23]

Do you guys think this would be a good fixture for my 20 gallon long tank?CD-32827

30" x 5-1/2" Saltwater; 48 watt $94.99 $75.99http://www.drsfostersmith.com/product/prod_display.cfm?c=3578+3733+13822+16770&pcatid=16770

I currently have a dual fluorescent fixture.
Right now my tank is Fish only with Live Rock..and one snail...
I just want the light because the blue lighting looks nicer. This fixture doesn't have a night light feature which is something I want also. Can you guys recommend me a t5 fixture with a night light? I may do corals in the future.

I suppose it really matters on what kind of reef animals you would like to add. If you want free reign, I would be looking at minimum 5x wattage. I have 130 watts over my 20h.
