I'm in the process of setting up a 180g, 72x24x24 tank that will be mostly SPS. The tank is on an angled wall is the basement and is visible from three sides. Here are the options I'm considering. 4 Tunze 6095's on the back wall. 2 Tunze 6105's, one on each end and 2 6095's on the back. 2 Maxspect Gyre, one on each end. 2 MP40'S, one one each end. I'm leaning more towards one of the Tunze setups. Let me know what you guys think.
