Ever wonder what happens if a big 200plus tank blows

[gobytron]

pardon my ignorance, could you also blast each pane with a pre determined PSI as well?

I would think you could easily call your tanks the safest glass on the market if you did have some kind of testing process...

And we all know aquarists, for the most part, love reasons to spend more money on better tings.

I wouldn't see any point in that as failure typically only occurs as a result of defects in the seams during tank assembly. Glass is glass for the most part and failures don't occur from defective glass unless it was chipped during cutting or assembly but that would also be captured from a standard hydrotest.

but wouldn't blasting the glass put pressure on the seams?

meaning blasting the assembled tank, from the inside, with a predetermined PSI?

If you pressurized the whole assembled tank then yes but pressurizing with air alone would not be advisable. Water or fluid is used because it's incompressible, if a leak forms during testing it basically just leaks while using air or gas will expand and potentially cause more damage if a leak forms. Basically without fluid you could be building a bomb which is not something you want in your shop. Also this test wouldn't be something you would do on normal or average tanks, really just large/specialty custom tanks that would have a large investment behind them. The cost of doing such a test would be high as the builder would probably spend more on producing a stronger tank to ensure it passes a hydrotest. For example spending more time on sealing (stages), machining all edges including non- exposed and/or using thicker glass.
