I have a Tek 4 bulb T5 fixture over one of my tanks and the 2 bulbs in the front of the fixture have stopped working.
I switched out the 2 (I know for sure are working) bulbs from the rear with them and those won't light either.
I am assuming the ballast is shot but want to know if there is any way to be sure that is the issue before I purchase a replacement ballast.
Is there something else that may be wrong with the fixture?
I placed the 2 daylight bulbs in the rear so at least the corals will be fine but need to get this rectified asap.
Any light you can shed on this is appreciated!
