Berlin AquaDom explosion - what went wrong?

Or some diligent person desinfected EVERY surface.
The fumes of disinfectant could also added to the disaster to.

I think we can safely rule that out, since it was completely out of reach, and there’s no way they’d leave cleaning up to a regular maid service even if it had been in reach.

…
The level of uninformed speculation in this thread is particularly bad. Why not use at least the publicly available information?

I’ve seen discussions elsewhere where people are claiming the atrium was barely heated above ambient, and that the “uninsulated”* glass roof would have led to the air at the top being colder than at the bottom… :palm: :-DD
* more speculation by someone who apparently is unaware of the existence of double- and triple-glazed insulated windows.
I looked at the hotel website. There is — well, was — a bar in the atrium. I agree with you: absolutely no chance that space was not heated to indoor temperatures.
Besides, I’d think that the requirement for the water to be kept at its stable 26°C would have largely negated any advantage to heating the air less. They’d just have to put more energy into the water to stop it from cooling off too much.

I'm not so sure about that. During Covid, anything and everything got liberally sprayed with whatever product was to hand that said "anti-viral" on the label, and this was seen as a Good Thing (TM).

It is possible that the bar was using infrared heating to reduce costs, whilst the air was kept colder. But it does seem a bit odd for a 'premium' location to do that. But, after last orders, maybe they did reduce the air heating power to save money?
Regardless it's clearly a terrible design flaw if colder air could lead to the failure of these structures. Heating systems fail sometimes!
Though I do agree keeping an aquaria at 26C year round is surely a significant consumer of energy, probably the biggest single consumer in the building.

No, definitely not! The aquarium was not within reach of anyone’s hands, other than the divers who fed the fish and took care of the enclosure, and they’d know damned well not to use anything improper on the aquarium. (Nor would they use any toxic chemicals, since many cleaners are toxic to marine life.)

The outside of the tank was over 8 meters of of the lobby floor, so no passing by to stick anything to it.

There is literally no need to disinfect a surface that has no contact with people.
