It doesnt really matter how much stray voltage is in your tank as long as it is reduced to zero when you fit a grounding probe.
Basically if you have a proper electrical breakdown then the probe will be able to get rid of the leathal current and trip your electricity out.
If you didnt have a probe then there is always the possibility that your tank would stay 'live' with a leathal current until you next put your hand in the water, then you would become part of the circuit to earth and you would recive the electrical shock.
Basically in a nutshell, if you have a probe fitted and your tank is at zero volts then you are fine
have you thought about fitting 2 probes? this is just a back up incase anything goes wrong with one of the probes.
(I have two probes in my tank)

P.S. Im an electrical engineer
Thanks Statto, that helps a lot. 2nd probe isn't a bad idea, you can never be too careful.
