Tank is 36"l x 12"w x 24" t. What is best choice? 175 Mh or 2x96 pc or 2x96 vho. I'm going to start with some hardy corals and move up from there. Also would a 4x96 vho be too much for this tank. Someone has one for sale used. Man I've read about lites till my eyes were bleeding. Just trying not to have to buy twice. Thanks for ideas. Also any starter coral suggestions
