I had a cable fault on one of my powerheads and was getting 120v in the tank, good thing the floor was dry when i found that. I want a ground probe but have not put one in yet.. that was not tripping the gfci either, although it probably would have with a probe.
after i fixed that 20-25v was what was left from all powerheads running.
most was coming from my internal powerheads , the rest from a heater i no longer use.
do the DC tunze pumps induce any voltage into the tank? or do only the externals<vortech> get that claim?
