I'm trying to make a to-do list of things to figure out. I need to determine lighting so I can build the canopy to accommodate it. I've only used the current USA loop. Im thinking about a t-5 led hybrid. 60" fixture I think will cover the 72" tank enough, as the back corner overflows take up some space on either side. The goal is to have a light that will cover well enough to have no shadow from the black center brace.
