Is Hagen a Drillable Tank?
 

I have a 135gl tank that I am trying to sell and someone has asked if it can be drilled. Do these tanks have a tempered bottom?:question::question:

Get a pair of polarized sunglasses and have a look at it. Have a look at the windows in your car for comparison. Don't look at the front window though

I have a Hagen 77 gallon and was stumbling around one of their web sites the other day. According to their FAQ page, they do not use tempered glass on any of their tanks. Link provided below, should answer your question.

I know Hagen used to use tempered glass on the bottom of their bigger tanks, but that was years ago so maybe that's changed. I would email Hagen directly if I were you.
