I think it is better/best to have a gound probe rather than test it using you body.. a power trip will only stop the activities in your tank for most few hours and if anyone touch on the leakage.... who knows the cost.

I believe the grounding is to detect any leakage in the tank. As the grounding is connect to the ELCB (Electric Leackage Circuit Breaker), the CB will trip (cut off the power supply) if there is any current leakage. This work same as the water heater you use in your bathroom.

My 4 nemos all sleep by laying on the LR.
