The 700 gal indoor sunken garden project

Looking good! But what if your equipment malfunctions? Than you'll have a real flood.

Not at all I am worried about real flooding due to equipment failure or power outage.

The filtration adopts overflow system, and the new opening for channeling overflowing water is revised. It sits wider and allows excessive water to flow through without any serious threat from clogging. Any loose leaf or even dead fish (say that my big discus died without anyone noticing) will be flushed down into the sedimentation chamber. Live fish would be spared as they can swim back out into the main tank instead of getting permanently trapped. Water current is more like a stream, the height difference does exist but quite subtle and does not create waterfall effect.
The final chamber has improved overflow bulkhead to control overall water level. Any excess water will be self drained into the sewer, so that in practice I can do passive water change. Fill in fresh water for certain time or volume and it will mix in with the old one, while the excess will be trimmed down automatically.
