Let's talk about voltage in a system.

After feeling a tingle in a cut while I was touching my cement floor, I decided to get the old voltmeter out and take a reading.

Using a A.W. Sperry DSA-400 set to 200v ACV, I was reading 29v.

After unplugging everything I was reading 2.4v, took it as meter error. Plugged every pump/heater/lights/whatever in one at a time and saw no major jump, 2-6v depending on piece. Everything is less than a year old and I inspected all cord connections to equipment finding nothing out of the ordinary.

While grounding the tank to the cement floor, using myself, voltage dropped to 3.

Should I rule out a major leak?

Should I invest in a titanium ground probe?

Equipment:

Maxijet 2x 600, 1200

I also apologize in advance for having a post about the same topic as one already in the first 2 pages.

Also, I don't normally stick my hands in the tank with cuts, so I don't know if this has always been going on.
