I'll have to do some drawings to visualize it but I am not going to use a
center brace for the glass. The glass has a 45 degree bevel around the edges and
I am going to slide the two pieces of glass together and use a silicone rubber
seam to seal between the two pieces of glass. there will only be a 24"
vertical expanse of glass so it should work well. I plan to use 3/8" plywood, maybe
marine grade if I can get a good deal locally. 3/8" is the most commonly used
thickness. Lots of marine plywood sold locally for the boat building market.
Lots of boats built in this area and building a plywood aquarium is kinda like
an inside out boat!
