Got A Short Tempered?

[hankstanks]

So my all-glass 29 is tempered glass all the way around.

Yea, it only took a few seconds for the glass drill press to prove that to use.

Any idea what/how I can tell if it is tempered? I want to use a 29 or 30L for a sump.

I might replace the pane on the 29 with plate glass and pre drill it but in any case. Any advice?

i thought there was a way you can tell by looking at it from the end. i thought they looked different than a normal pane of glass.

Here is a post on Reef Aquarium Guide that helped me to drill my glass tank for holding RO water.

I dont recall all glass tempering all the glass in a 29, sure it wasn't haste in the drilling process?

Ends up it was a Perfecto tank. Thing looks just like an All Glass
