Update time. Lucky I can still type.
Could not trace it to any one thing but a combination as I mentioned before. Both my Tunze 6080 & Hydor seem to contibute about half each of the 80v I measured. heaters and other stuff is fine.
Nothing registers with the ground probe in though and I can touch water to ground.
So working on my 90g today, moving things around and finding them a home. Of course my ground probe is in the sump still, which is not part of the 90g. I touch my forehead on the reflector, {halides off}, while working in the water and WHOLLEY MACKERAL. It flashed and everything, my forehead that is.
Crap, did that liven things up. Get the meter out again. Same measures as before. Put ground probe in tank and no current. Unplug pumps, leave ground probe in, plug Tunze back in and out goes my GFI/ARC fault breaker. Plug the Tunze into the other normal circuit and alls fine. But my ground probe is still in.
And thats the story for now. Why the heck does my Tunze leak 35v? Why does the other pumps do the same? Can anyone else measure any current in their tanks, without a ground, coming from submersible pumps.
