tempered glass

FYI this is my first post on R2R. I just purchased a 60 Gallon Frameless Cube for half off at Petco over the weekend and I was just going to transfer everything in my 29 gallon over. Once I was home and thought about it I decided I would rather drill it if I can confirm it is not tempered...

70 9/16" x 29" x 1/2" thick, tempered low-iron(starphire) glass. Was cut too long by the glass manufacturer and unusable for my build. $300 pick up in St. John, IN 46373.

So I am in the process or resealing a Aqueon 150 gallon reef ready aquarium with dual Dorso’s. My back panel is tempered so I can’t convert it to back drilled. Are dual dorso drains safe enough or should I drill the bottom of the tank to add an additional drain inside of each of the overflow boxes?

So I work at a discount store and this 55 gallon aquarium came on a truck last night. I immediately called dibs on it but realized its tempered glass and can't be drilled which is not what I wanted. If someone is interested, entire setup is $180 at Walmart so I'd like to get at least $100 or...

Researched for days and im fairly certain that it is safe to drill the back of the 120 marineland topfin aquarium. Does anyone have the same exact tank that is drilled? Only the bottom panel is tempered?
