Plan on picking up a Planet Aquarium 310 gallon glass 96.5" x 30.5" x 25" tank, and looking into an aluminum style stand like from Framing Tech. Question is how should I build the shelf for the sump and the top of the stand. The dimensions make it difficult to use plywood unless I use two pieces. Should I put some foam like the kind they carry at BRS on top of the plywood? Any suggestions would be appreciated!
