Also worth a look (per a Wikipedia source):
https://madisongroup.com/wp-content/uploads/2022/09/Investigating_Acrylic_Aquarium_Failures.pdfCurious that the failures seen so far are usually progressive though. You might expect to see an empty AquaDom with a crack running through the middle of it, not one that appeared to fail explosively, so I wonder if the failure method is different to that shown on slides 18, 19 and 21. Those failures seem to be almost universally at the adhesive joint, rather than of the actual acrylic. (Does this mean they do not use a plastic welding process to bond the sheets permanently? I know very little about acrylics to comment on whether this would be viable.)
Slide 20 shows a crack that was on a tank built by none other than Reynolds... (not sure who repaired it, but apparently that tank is fine now)
https://www.koreatimes.co.kr/www/news/nation/2014/12/116_169594.htmlSlide 27 is also quite interesting, I guess you really want to be approaching the 10
10 side of the time curve for a product like this, for a long term installation with a life of around 50-100 years. It did do over 19 years, or 6x10
8 seconds. Maybe the warranty was 15 years.

Anyone care to calculate the stress on the walls of the AquaDom given the weight of water?
Side note - it's crazy to me that there's so much demand for over-sized aquariums that there are several companies in the US
alone that specialise in making them. I can't imagine how many they produce per year to make this viable, but it can't be a small number.
