Who uses a grounding probe??

My heater is titanium. I think it basically accomplishes the same purpose.

I’ve heard this argument (a titanium heater is a grounding probe) many times but I have a 3 prong titanium heater and was still getting that “tingle” when reaching in the tank. Grabbed my meter and found 13+ volts of stray voltage. I spent the few bucks on the exact same probe pictured in the thread and voltage dropped to 0000. I always attributed that “tingle” to minor cuts on my hand , change in temp from ambient air to water temp or just my imagination. Been happening for quite some time until I took the 5 minutes to test for stray voltage. I’ll never run a tank without a grounding probe again.

Thankfully being in south florida I have no need to run a heater and use all DC equipment. I don't use a ground probe.

I found that it wasn’t the heater but a combination of my skimmer, return, and WaveMakers each leaking small amounts of stray voltage.

I have one in my display tank and another in the sump so I have coverage when the circulation pump is off. In addition to those 2 probes everything tank related goes into gfci outlets.
