Im just getting done polishing up my 220g aquarium and looking to start ordering equipment. The only problem i have no idea on what size of light to go with. Im looking to go with metal halides because i would like this tank to be a sps dominant tank. So my questions to all the members would be. What brand of reflector is best? 250w or 400w? what brand of ballist? Also how many 2 or 3?
