If you don't have a ground probe, it won't affect the inhabitants as the current has nowhere to go, unless you ground it with your body.

In either case, look into protecting yourself with at the minimum of a GFCI for the whole tank.
I run 13 of them because I want each piece of hardware covered individually without tripping the whole tank.
And I have a ground probe in both my skimmer and return chambers.

Later. BBQ and Beers

I should definitely grab a grounding probe at least. Installing the GFCI might be more difficult since I would have to move the tank in order to get to the outlet.


It does look like they have GFCI power bars. Probably easier for me to get one of those. At least that way I have some protection.

Nu uh. I wrote 'not' to use a grounding probe without a GFCI!!!
Breakers are only meant to trip when they get hot.
A GFCI senses an imbalance between line and neutral and only then does it trip. This will protect you if you stick your hand in the water.
Only having a ground probe will cause any stray/induced current to flow because you're giving it a path. Now when you stick your hand in the water you'll get zapped.

Either use just a GFCI, a GFCI and a ground probe, or forget I said anything and use neither.
