Hanging 2 sbreef lights

[sergifed91]

I have 2 sbreef lights 18 inch lights. My ai hrdas went out on me.vso I'm using them. I have a 125 gallon reef ready marine land tank. Hardly any corals. Will this be enough lighting for it. Bi think it's a 72 inch tank

Three would be nicer because if it's a standard 6 foot Marineland you have a top plastic frame with the three "compartments." That said, dependent on the corals and their locations, two would most likely work. They are pretty powerful.
