I am a girl
Last week I noticed a tingly feeling when I put my hand (which had a cut) in the tank. I checked it with the voltmeter and got nothing -- so I figured it was just the saltwater irritating the cut.
Last night I felt the same thing but stronger. So I had NDB check for voltage. Turns out I was doing it wrong! DOH! We measured ~40 v going through the tank.
Took in and out the grounding probe, and it made no difference. Maybe the probe isn't working??
We started checking the equipment. Unplugging the MaxiJet that runs my fuge dropped it by 3 v. Unplugging my return pump increased it by 10 v! (NDB says maybe when the return pump is plugged in it's acting as a ground?).
Two powerheads are plugged into one extension cord, and the other two powerheads are plugged into a second extension cord. When one cord was unplugged, it dropped by ~20 v, and when the other cord was unplugged it dropped by another ~20 v.
So it looks like all of my equipment may be contributing. My powerheads and pumps are old, I've had them all running 24/7 for the last 5+ years. Maybe it's time to replace them all.
Tonight I'm going to go to the hardware store and buy new cords and power strips. I'm going to clean everything off and re-do all my wiring (which is currently a rats nest that sits right above my sump and is covered in salt spray). Hopefully that will fix it. If not, it's Drs. F&S time :(
