I've been running 24" t5 on my 36x36 taNk thinking I can center it and cut off 4-6 inches off the edge. But Im Getting a lot of dark spots in the back corners. Looking for a pair of 36" or 48 I can cut to cover the corners. Center is OK with 24" since my over flow doesn't need lights. Please pm me if you're local. Not looking to drive far. Thanks.
