I wonder how that idiot would feel if he was water boarded to circulatory failure and then revived with a bare lamp cord... good grief what is wrong with people.
I agree.

Exactly! It also doesn’t help that human body is much more conductive on the inside. Maybe the surgeon should just place a grounding probe next to the kidneys when operating. Lol!Yeah - can't have nuisance trips on life-safety devices. Whole different ball of wax in an ER or ICU.
In fresh water - a grounded probe is out of questions. If you get fields in freshwater - the current will go through the body of the fish because the conductivity is higher than the surrounding water - electrofishing. In saltwater - the water have much higher conductivity than the body - the current gooses outside the body - no harm to the fish.

Pertinent I hope. Effects of electricity on fish. Sometimes electrofishing methods are used to clear schools of undesirable fish:
I think BeanAnimal covered the question perfectly. A simplified way to look at it is the "the bird on a wire" scenario. Very hard for the bird to ground itself when so far away. When a grounded source (opportunity to ground) is placed in near proximity then it becomes more dangerous for you. The good news is that a GFCI will protect you if you have a grounding probe. That's why it's especially imperative to have a GFCI with a grounding probe.

You have a source of voltage leakage in which water and electricity do not mix and you are the ground. A ground probe will offer a safety but not a resolution. You want to start with sump and unplug return pump. If it stops- thats your culprit. If tingle still present, plug return pump back in. If there is a heater, do the same. If tingle still there and no other electrical components, go to tank and start with power heads and so forth until you locate sourceHi all, I’m having a bit of a confusing situation going on that I need some help understanding.
I recently felt a strong tingle when working in the frag tank and bare feet on concrete. I am usually wearing shoes so never feel a tingle. I did a bit of diagnosing and realized that I am feeling the tingle only when the titanium heaters and or chiller are plugged in. I know from previous experience troubleshooting stray voltage a few years ago that both of these items act as grounding probes. What I mean by that is that I do not read any stray voltage on the voltmeter when either of these items are plugged in. Currently I am only reading about 1 V stray voltage when these items are unplugged and I do not feel the tingle until they are plugged in. I should also mention that these items are plugged into an Apex energy bar and the respective outlets are powered off. So these items are not energized when I am feeling the tingle.
What this is indicating to me is that the Source of the tingle is actually coming from my homes ground through these devices and into the tank. These devices are importing voltage into the tank rather than grounding it out. Does that make sense?
Does this indicate something wrong with the wiring in my home? And is there anything I can do about this other than swapping out the titanium heaters for glass and keeping the chiller unplugged when it isn’t needed? Or do I have this all wrong and something else is going on entirely?
Yes, I’m familiar with basic stray voltage troubleshooting. What I’m saying is, the chiller and titanium heaters are the source of the tingle, and they are providing the tingle even when the outlet they are plugged into is powered off. What I think this means is my home ground is the source of the tingle via these two grounded items.You have a source of voltage leakage in which water and electricity do not mix and you are the ground.

Gotcha and i would check the ground with a meterYes, I’m familiar with basic stray voltage troubleshooting.

No - it does not make sense, but is easily checked. Potential between two ‘ground’ points can exist and current will flow. Drive 2 rods into a field some distance apart and connect them to a meter, current is likely going to flow.What this is indicating to me is that the Source of the tingle is actually coming from my homes ground through these devices and into the tank.

Sounds like something bad happening at the outlet. Get one of those outlet testers and see what it shows.Yes, I’m familiar with basic stray voltage troubleshooting.
