Just built this stand for an 80 gallon shallow reef. 48x24x16 tank dimensions. Stand is 38" tall. Will I need a center brace in front center? (It will have a 3/4" piece of ply on top as well and a 4'x6' piece of 3/4 oak to help with any imperfections in the carpet and pad under it. (Apartment or I'd rip it up). It will also be about 6-8" away from wall to allow space for reaching behind if necessary as well as clearance for tack strips.
