Titanium ground probe to ground tank good or bad

[BBQHILLBILLY]

I would like to hear some experiences/opinions
I do not use a ground probe. I have had a koralia powerhead produce voltage and now a quietone pump produce voltage in sw in 1 week.
I will throw them away. got shocked. small shock.

I guess its best to buy NEW pumps.lol
Without the ground probe I can identify which ones are going bad and throw them away.

If I had a ground probe I would never know which one is bad.

On another note a ground probe may save the livestock and reduce stress.
