I have a fairly new Nano Cube (12 gallon) that I started setting up as a reef. The day I was going to put one of my clowns in, the lights stopped working. When the timer clicks on, the light will flick on, but only for about half a second. A minute later it will flick again. Over and over but it won't fire. Do the PC bulbs have some sort of starter in them? Is it the ballast? And is this something that's common with these things?
