I have 72g bow too that leak at the bottom. I found out that the bottom glass is sagging when you put too much waight on it due to weak cross brace. What i did is, resilicone the tank... got a styro from home depo (the orange one) and cut to the shape of what ever glass is expose at the bottom (not touching the black plastic base) and tape it there to support the glass from sagging or flexing. It works grate for me.
