I can't decide on the lighting should I upgrade or not? The tank is 48"L x 18"W x 16" Tall. Right now I have 2-175w xm 20k with four 28w pc lights over the tank. Two pc are 50/50 and the other two are 03 actinic. Do you think this is enough light to have SPS only in the tank? There is about 2" of sand on the bottom so I have about 14" of water depth. Should I upgrade to 2-250w xm 20k's without supplement lights? Please help with my tank. Any ideas would help. Thanks
