I am going to set up a 72 gallon reef. I'm pretty new at all this so I need help with my halide selection. I don't know where to start at all. For excellent halide lighting how much should I be spending? I want to know around what it should cost BEFORE going into my LFS. Like I said I really don't have a clue where to start. I need to know size, what wattage and spectrum. I'd like to be able to house 100% of the corals out there. Thanks for your help!!
