On my 220 gallon SPS tank I have 3 60" VHO Actinic bulbs on an IceCap Ballast. I have had the bulbs for a year. Recently they stopped turning on with their usual timer. When I unplug and then plug them in, they flicker on for a second and then turn off. I thought it was unlikely that all three bulbs died at the same time... so I'm thinking it might be a ballast or wiring problem? What do you think is wrong here?
Thanks for your help!
