If you could have 220V for your tank, would you?

It's not different. Voltage varies across the country. 110-120v is normal, and 220-240v is normal ranges. Come call it 110/220 others, like me, call it 120/240. Just habbit. Now, taking as 3 phase power into a panel actually makes 110v and 208v It's hard to explain, but has to do with phase vectors and a bunch of trigonometry.

Just remember, Lower the voltage, the more current is needed for the same Power/Watts.

And FYI, a HP for an electric motor, is equivalent to 746Watts, regardless of voltage. Watts=HP.

So, for a 1HP motor, running at 240v =3.1 amps
same motor running 120V =6.2 amps

It's the same Watts(746) But the current draw on the wires is less.

now, if it was a 10HP, it would be 31amps or 62. THAT'S a large cable size difference.
