I have a ballast that has the "old" metal halide bulbs in it, I want to have a reef tank and I was wondering if I should just use the "Coralife mini compact fluorescent 50/50" bulbs that just screw into the old metal halide sockets, or break down and buy a new ballast that will hold the fluorescent bulbs?. The mini compact lights have "50% 10,000K Daylight, 50% Actinic 03 Blue" is this okay for a 30 gal reef tank?
