I need to buy a new MH ballast. I have a bluewave on one tank that seems like it is doing okay, but I just want to see what the long time metal halide users have to say before I buy. I can't spend too much. I need to get a dual 250w, and right now I am running aqualine 10,000k on the sps tank. I was looking at the galaxy since it has a 5 year warrenty. Suggestions?
