Just my observation here... But when I have had to troubleshoot electrical issues in the past I have found that induced voltage seldom gives much of a shock.
Like the red wire in a three conductor cable if it's isolated on each end will show a voltage on my volt tick because of the induced voltage. When I grab it with my bare fingers there is no shock because there is no actual power behind it.

Is the original poster able to tell us if the shock he receives is continuous or a one time hit? Might tell us something... A one time poke might lean more to induced, continuous would be voltage leak. I get a good continuous shock from the aluminum siding of my trailer when I plug it in with a 2 prong cord.

Other issues could be bad bond or neutral connections in the house or power bar wiring... really to many variables to troubleshoot over the internet. It did make me check my tank and I'm down to .1 or .2 volts with powerhead, skimmer pump, 2 submerged heaters, and a DC return pump.
