I've seen a CO2 overdose (not caused by end-of-tank dump, but rather
due to a faulty pH probe/controller), which killed a bunch of fish in
an open-top tank. The deaths were caused not by lack of O2, but
rather by the massive amount of CO2.

ride to the welding shop. The only way to get liquid from the
pressurized tank to your aquarium is if the pressurized tank has
liquid in it and it falls over.

Even then you probably wouldn't get liquid CO2 out. It would be
stopped by the regulator, but it might damage the regulator.
