Tempered glass?

[cactusmoe]

Ok I have a 55g aquarium. On the bottom it says made by D Z on one part and All-Glass Aquarium ® on another. Can any one help me figure out how to know if the sides r tempered ( besides taking it to a glass shop)

you can do the temper test .. its pretty easy .. put the tank out side on a sunny day and look into the glass if you see folds in the glass it will look like glass stacked on top of glass then its tempered .. or you can use a pair of polarized glassed and you can see the folds better ..

U mean like look at it from an angle or something?

no where the corner of the tank is .. look into the glass that way or go get some polarized glassed and do the same thing ..

If you have a laptop you can hold the screen against the glass then look through the tank at the screen if you see a bunch of vertical lines onscreen it's tempered if it just looks like a black screen it's not
