Metal Halide. I have a 46-gallon bowfront tank by all-glass aquariums. How many watts of metal halide should I get? Also, is Ushio a good brand? I found a pair for sale REALLY cheap! 250 watts *EACH* 10,000k.
what about this? "Coralife Metal Halide 150 Watt 10,000K HQI Lamp" maybe two of those? Can I just screw this into my flourecent fixture (that came with the tank) or do I need a new hood?
