    @rygh do you have float switched in your setup in the sump as I have heard that cheep yellow wired eBay/Amazon float switches and other float switches when they get old they leak voltage into the tank and could cause issues with the conductivity probe....just a thought...

    I tested it by putting tank water in a small vial. No difference.
    So not stray voltage.
