Used Visio 120G tempered glass?

[Pedal Dangit]

I'm not finding info on the website if any of the panels are tempered or not. I just got a deal on a used Visio tank and hope to drill the end glass.

does anyone know? or how do you test it? I have seen something about putting a laptop in it and looking with sunglasses?

thanks in advance.

Best way to tell, if you cannot get info from the manufacturer, is to take a pair of polarized sunglasses, and look through the glass, if you see black lines through the glass, its tempered. I'll attach a video on how to do it:

thank you. That video should be in a "sticky" at the top of the DIY section. maybe in a thread just about drilling tanks
