I just purchased a 20x20x8 frag tank from Advanced Acrylics with over flow and two racks. I am trying to pick the light I need. I am interested in having soft corals mainly and maybe try a few acros someday. I had ordered the Kessil 160 but the place was out of stock and refunded my money so now I am back looking again. I am looking at the xt-nano. I think I want a hanging/arm fixture, I like the top viewing option.
