1. use a multimeter one tip in the water and the other in the grounding slot of a plug
2. set for AC and systemactically unplug things

Is this correct way or is there a better way

This is the exact approach that we used to troubleshoot a problem a while back.

As far as the GFCI / Grounding probe situation... I'd personally prefer a little voltage went into the tank and notice it than have something trip the GFCI while your away and have a tank crash. If I were to do it, i'd put a grounding probe in a GFCI circut and have something obvious but not essential to the tanks survival running on it. This is assuming the grounding probe doesn't trip the circuit in the first place... Or run some voltage monitoring in the tank.

If it really comes down to fish dying vs me or another human dying, I choose GFCI.
