3/8 is fine for the tank i have to figure out how to do mine, maybe
i ahve a 62 gal custom that i made
36x20x20 and its 3/8" I dont need a brace it hasnt bowed either .
the sides are added there for extra strenght and water splash too. IMO
2" is acceptable for the glass if you can get it cut if not go with 3"
