We have an industrial unit which has a mice problem. Every time I go to B&Q (home hardware store for non-UK folk) with the intention of buying mice traps, I just can’t push the button. These mice are destroying our stock, but I just cannot do it. I would be a terrible fisherman.
You can get catch-and-release mice traps, and then dump them in a field or on a competitor.
From an engineering perspective these sorts of acrylic tanks are a nightmare to ensure they are safe. The seams are impossible to inspect rigorously so the only real way of checking that they are safe is to load them with an excess pressure ( https://en.wikipedia.org/wiki/Hydrostatic_test ). This can't be done with a tank of this size so the engineers can only real fall back on giving the tank excessive safety margin…
They could have steel bands providing reinforcement which would be just slightly obtrusive at some angles, but boy, now it would have bands and well, it's not an uninterrupted glass [acrylic] cylinder.

Would it be possible to construct a seamless acrylic tube, maybe on-site?

Doesn't seem crazy, my tires hold 38 psi.
PSI is a measurement that can be hard to translate between various items like tires and tanks and foundations: https://www.engineeringtoolbox.com/building-foundations-load... Massive tractor tires can be 50+ psi and when they pop it is devastating.

A tropical aquarium is keep at the same temperature. Unless somebody would disconnect it to save energy or the termostat[s] would fall, shouldn't have experienced a lot of changes in their volume by this.
The hotel was required to reduce its lobby heating due to energy sanctions.

> After the strange coup try in Germany the last week, I wouldn't discard still that is not another destabilization attempt by some hypothetical agent. How would that work? Is this site important enough to destabilize the country?
Only two people injured after a million liter water wave was a miracle. Could have been much worse. But I'm probably just hypothesizing too much [again] while trying to analyze the case. It just feels strange coupled with the last long chain of strange events happening right now. To be fair, twenty years are a lot of time for an acrylic tank.

Have you considered outsourcing? To a cat (or cats) or a pest control company. The pest control company will probably check and close off opportunities for mice to enter the unit, which cats won't do, so you might want to consider retaining both options. Warehouse cats can be nice warehouse companions too (depending on what happens in the unit). I've had to do some mouse removal work in my forest adjacent home, and i…
In Costco they sell this cat food called ‘Maintenance cat’. Maybe we need one of those cats.

- 15 segments of acrylic glass
- 12 segments for the outer cylinder, 3 for the inner
- all segments worth 4 million EUR
- 200 wall thickness
- shipped in a steel construction
They did not say it, but from the video it looks like the segments were assembled in at the destination but not in their final location.
EDIT: I misunderstood, looks like the outer cylinder was assembled in-place, the inner one on-site and then lifted inside.
For completeness, here is the video, but it is in German:

What's the best material for a tank like this, if not acrylic? Normal glass? Not educated on this subject.
