I learned to properly inspect a used tank before buying it. I being an idiot bought a tank that the woman said her husband re-sealed.... Well he did reseal it... the tank measured 48" x 24" x 30" 150ish gallons... the bottom looked great where he re-sealed it. But something was different... instead of it being one solid pane on the bottom it was two panes that met at the middle support. I figure it was nothing and that it was some sort of older design. While scrubbing the tank clean of the 3 year old dried up green stuff on the bottom I slipped and put my hand through one of the bottom panes... it was only 3/8inch thick. So now I have stitches and I wasted 275 $ on a tank some one jurry rigged together.
