Electricity Problems

Gotta unplug one thing at a time and stick your hand in after each item lol eventually you will not get shocked when you unplug whatever is causing the stray voltage. I'm I'm sure this is not the correct way but has worked for me in the past good luck.

I did exactly that a week ago and I couldn't find the source. I unplugged everything too.

One thing you could do is take a voltage meter and put one end on the grounding probe and one in the aquarium. Then unplug things one at a time to see what is causing the stray voltage. This technique is very similar to just unplugging things one by one and getting a shock.

Try those two but let your tank build up a voltage between checks(unplug everything get a shock then plug the first thing in wait 5 min if no shock unplug it and plug the next device in).
