Stray voltage

[Rp8]

Is 0.176v worrisome in the tank? There is multiple equipment running in the sump. That’s what I. Got on my multimeter

Bump

Thanks guys

Seems pretty low. Doesn't saltwater on its own carry a certain charge at idle? I could be wrong...

I’m not sure, that’s why I was reaching out. Thanks

Hmmm according to this article anything over zero indicates stray voltage.

There are also a few long winded threads here on r2r on the topic. Looked through those? Sorry I don't have a specific answer for ya

do you have a ground probe in the tank?

Not high but there is some polarity.
I would recommending running a ground probe always.

Thanks. I’ll trouble shoot to see which piece it is. The heaters are years old. Hoping that’s it, since I have replacements

I have one on the way now

Let’s stir some ish up: Shouldn’t we be concerned about stray current, instead? Lots of devices probably have a magnetic field that propagates throughout the tank that would cause a voltage reading. If your tank is insulated from ground and other devices, then no current can flow. It’s the flow of current that does damage.

Measure with all equipment off. Depending on the type of metal in your DVM probe you could be seeing energy created by the salt in the water.

And for the previous reply, voltage pushes current, so without voltage there will be no current.

Hope this helps.

Voltage is a potential for current to flow. Without a difference in potential, there isn’t any current flowing.

I think that this topic needs a further look. There is a difference between an E field being produced by your gizmo and a fracture in your gizmo that exposes a “live wire” to your tank water.

I’d think that we should be measuring/monitoring current flow if we are going to add a ground probe. If you see a sizable increase in current, you probably have a failure in your gizmo.
