If you do have stray voltage, adding a grounding probe will give it a path to ground. This is not good unless you have a GFCI
With a multimeter set to 120VAC, put the red (positive) probe in the tank water and the black (negative) probe into the d-shaped socket in any outlet
If you do find current in your tank, unplug one piece of hardware at a time until you find the culprit
Any current above a couple volts should be investigated, but sometimes you can get a reading just from lights above water creating a 'field' (for lack of the proper term)

+1 however if you can put your hand in the tank with no issues, not likely stray voltage.
I had a skimmer pump that would turn off and on. I narrowed it down to the pump after it kept randomly overflowing after a few days of perfect skimming. One day i was looking at the sump I heard a rattling noise, then silence.I put my hand under both pump inlets, and sure enough one wasnt running. After replacing the bad pump, it was perfect. Pump happened to be a sicce PSK2500. I would replace the pump.
