As stated by P but differently:
The average difference of potential between a persons feet and head is 500
volts.
But there is no current to go with that potential.
One of the coolest experiments I did when I was first learning about such
things is suspend a wire 5 feet in the air insulated at both ends. Then
ground it through a 10 megaohm resistor and measure the voltage. (To prove
the previous statement)
Same holds true with the tank UNLESS there is a damaged component.
In that case, the said tank components had BETTER be connected to a GFCI!
Otherwise, a failure can boil your tank!
As for the health benefits, I think it is like wearing a magnetic bracelet
to cure carpel tunnel syndrome.
The grounding probe is for safety when used with a GFCI only..
IMHO
