On Monday night (probably about 1/2 hour after you left, LOL) I just busted a 10g tank (bumped something, which knocked over a plant that fell on it. Plant was a writeoff too. Ooops.). Anyhow, it has 3 unbroken panels on it (the bottom, the back, and the left side .. I'm not sure what a typical 10g is. Something like 20x12x9? So one piece 20x12, one piece 12x9 and one piece 20x9 .. if I understand my geometry correctly
). I was about to haul it off to glass recycling. If you want it ..... let me know. It's not very thick glass. It's thicker than 1/8" but less than 1/4". I'm guessing it's 4mm, maybe 3mm, I'd have to check with a ruler.
