What's an accepable level of stray voltage in a saltwater aquarium?
Is a grounding probe just a cover up to the real problem (after all, there's still voltage in the tank, it just has a way out now) or is it a viable solution rather than replacing equipment?
I'm guessing this level is really bad? I bought this thing today because my finger felt funny when it touched the water when I was doing a water change.
Should I check each piece of equipment one by one?
It reads 21.5.
EDIT| I put the black probe in the water and the other probe on my finger. I didn't have any metal near by to touch it to.
