Grounding Probe...Tank or Sump?

Yo!

I bought a grounding probe and in the directions it says not to submerge the top of the probe under water.

Originally I was going to place it in the sump, but because I have a shallow sump, I thought I would place it in one of my overflows.

I figured that if there's any stay voltage somewhere, removing it from the display would be better that the sump, but sometimes my simple logic doesn't work.

Any ideas? :)

If you have stray current in a tank, it will be in all of the tanks you have connected to it. So it doesn't matter, if it's in the sump/overflow/display.
 
Ditto.

The current will find its way to the probe regardless of location. Put it wherever it is easiest to mount and run the cord.

You guys are such smarty pants!

I think your overthinking where you think you should put the probe

Go a head & tell him where to put the probe.
 
You should put a probe in both the main tank AND the sump. That way if the main pump fails, and the drain water is no longer connecting the main tank and the sump, both areas are still protected since in general, there are electrical devices in both areas.
