Change ballast or new light

[jones2270]

I believe that ballast has gone out on my Nova Extreme Pro, how hard is it to change out or could it be another problem? I have also thought about changing over to metal halides, what would be a good fixture for a 33 gallon cube?

Ballasts are relatively easy to replace(assuming you are comfortable doing very basic electrical work.)

The hard part will probably be finding the same ballast. You'll likely have to replace it with a different brand's product.
