I will soon be building a 25 gal tank. It will be 36" wide, 16" high and 10" deep. I will be using 1/4" plate glass.
On another list I read where they bottom of the tank should support the front, back and two sides. But when you look on the web most sites recommend the bottom glass is siliconed inside the front, back and side glasses. Here is one site that actually recomends using 1/4" dowells as spacers under the bottom before applying the silicone, thus the bottom glass is raised 1/4" above the sides/front&back. Wouldn't this cause the siliconed joints to stretch and possibly fail?
See: http://www.garf.org/tank/buildtank.asp

I want to build it right the first time, AND I don't want any disasters.

Thank you
