Money. I own 250 gallons , 125 salt and 125 fresh, without being rich.those tanks are expensive to maintain and the stocking isn’t the cheapest aswell.but most of it is used.point being you can maintain bigger tanks than your wallet „should“ allow with patience.what does a tank like this cost? 10 grand? Doable even without being rich.
The ones I've seen in videos for like the "mermaid show" tanks just continuously pump air. At a quick glance, it looks like you need a special kind of low pressure air compressor and a long tube basically, though most of the equipment is built for deeper situations than an aquarium. Systems for shallower diving look like they're somewhere in the range of $500-$1k? I don't know what it costs to refill scuba stuff or get certified, but you might end up simpler and cheaper in the long run by pumping air down there. I'd have to do more research though, definitely not something you'd want to screw up and find out the hard way that you're doing it wrong.
A bigger tank also gives more room to understock and just let the tank maintain water parameters on its own. But most people don’t want to look at an overgrown jungle I guess.
