As I said in the first place, I would not feel confident using that panel of glass. (the back one).

And I know that this is a completely seperate type of scenario and type of glass, but glass is very unpredictable, think about your windshield when you take a rock, it hits, nothing really happens, a small mark, glass cools down, heats up, and then you have a crack all the way through.

That is why I was not going to use the tank. I actually am in the process of setting up a 600 gallon tank, and could have used this as a sump, and chose not to. I have no trust in glass that has taken that kind of abuse, and in the end, it might just not be worth it.

That being said, I hope it all works out for ya.
