DO NOT use tempered glass in aquariums. It does have the structeral

Hey Carl.
I have to wonder then....
When I bought my All-Glass 75g the bottom is made from tempered glass.
You could get a version that wasn't, but since I wasn't going to drill
the bottom, I got this one.
So now you're freaking me out. = O
If it's not good to use in a tank, why would they make them with it?
There is a sticker on the bottom that says "Bottom is made from
tempered glass for stregnth and reliability. Do not drill."

Perhaps because the greatest load is on the bottom plate. From the
comments above, I thought it strange to read that tempered glass was a
no-no when I've had numerous tanks using tempered glass. But maybe the
float (plate) glass are used for the walls only. I couldn't remember the
stickers I read being specific to which part of the tank was tempered.

The op didn't make it clear on stress/strain factors or ratios. But if it
helps, within a given dimension, tempered glass is far stronger than
stainless steel and the stress/strain ratios are linear.
