Hey everyone.......I will soon be getting a new Coralife 48" Compact Flourescent Lighting system for my 55 gallon tank. I'm really excited! I will also be needing a glass canopy. My 55g is from Walmart and has the center brace. Should I get 2 24" glass canopies, or a 48"? I've read where some that get the 2 24" are too big. Will a 48" be cut into two separate pieces for a center brace? I'm really confused on which one to get. Thanks!
