Stray Voltage

[Magickiwi]

I use a grounding probe. Partly to eliminate stray voltage in the tank but also as a safety item for me. If I'm monkeying with my arm in the tank up to my armpit and I accidentally knock the skimmer, or a light fixture, whatever into the tank I'd rather blow a breaker than fry myself.

To me it's like playing with toasters while you're in the bath.
