Another problem with the setup is that he will stunt the fishs' growth.

A 10-gallon tank with GUARANTEED clean,fresh water can stunt the fish's
growth?
If the fish had no place to swim properly, I can see a problem with the
10-gallon volume.

While I agree about the general 10-gallon per goldfish "rule", the only real
evidence I have been able to find is that the lower the water volume per
goldfish, the less time he has to react to a brewing chemical problem in the
tank that could harm the fish.

I can also see why a more toxic water environment could stunt a fish's
growth.
But one could have a more toxic water environment in a 50 gallon tank than
in a 10 gallon tank if they don't deal with the problem.
And it is easier to dilute a given concentration of toxins in a 10-gallon
tank than it is to dilute the same concentration in a 50-gallon tank (i.e.
less clean, fresh water required for the 10-gallon tank).

I wish someone would manufacture a device that could constantly monitor Ph,
Nitrites and Nitrates, just like Seachem has a device (Ammonia Alert) that
constantly monitors free Ammonia in the tank.

The only time I can see a 30 gallon or larger tank be truly safer for the 3
goldfish in question is if the larger tank could somehow establish a
self-contained ecosystem that the 10-gallon tank was not capable of.
