Here's the new tank I just built. I have to wait 72 hours to have it cure...so no water tests until then. I added a center brace to prevent bowing (as i had that problem with the 10 gallon).
The third picture is a macro of the seam to show that there are no bubbles! The glass may not be clean! (I didn't clean that side as well, as it wasn't getting sealed). BUT...there are no bubbles in the seam! WOO HOO for the first glass tank
