I currently have http://www.marinedepot.com/Coralife_48_Inch_Aqualight_With_2_65W_Actinic_2_65W_10_000K_Lamp_Straight_Pin_Base_%28with_fans%29_48_Inch_Power_Compact_Light_Fixtures-Coralife-ES53124-FILTFIPCFE-ES53106-vi.html as my lighting but I was told that isn't adequate for a reef tank and need something like http://www.fosterandsmithaquatics.com/product/prod_display.cfm?c=3578+3733+13822+21461&pcatid=21461 or MH. Is this person right? If so why are the lights with lower wattage better or am I missing something? Thanks for the guidance. 55g tank
