Electric Current in tank - where is it coming from?

Anybody ruled out these bad boys?



Bet they can trip the GFCI and shut the system down!

And why did I become so adamant? Because as safe as this hobby is, electricity and water can be a deadly combination. What happens if its not fixed properly and proceeds to get worse, then add (God forbid) he ends up standing in some spilled water when he does a water change and happens to do something as simple as put his hand in the tank to deflect the water and not disturb anything. That current path is through the heart!

Happend to me,was setting up a tank after a move (water on the floor etc) and a pump must have gotten damaged during the move since it wasn't working. I stuck my hand down the tank without unplugging it and woke up on the ground, wondering what the hell happened. Wouldn't recomend it.
