    And use a single strand wire to connect to the thick prong on a wall plug

    Final product, this probe is in use already for 2 years

    Note the little bit of rust after 2 years. Will take all my probes out tomorrow and sand them clean again. Anyway, these rods are so cheap, I could just as well chuck the old ones.

    Just bend the end so that it hooks over the sump rim. So that the connector block is outside. Do not want it to fall in and expose the copper to the tank.

    Thanks for this. The explanations were easy enough but pictures are always way better! I have a 1.6 mm surgical stainless steel rigid wire. Maybe a bit thin but with the minimal rust you've shown i think it will last a long time.

    Remember to wire it to earth prong ;)

    Also the rust isn't so bad, it will remove phosphates, Ferric Oxide anyone :)

    @RiaanP great illustration
    @dallasg good point, although it will have to be a hellavalot rust to be effective

    Oh, be sure that the wall plug or extension is grounded. OK, Duh...

    The probe in last pic already saved me or my tank.

    I cleaned all my pumps, took them out, scrubbed them clean, run them in vinegar. Cleaned al pumps, heaters even the thermometers.

    That night, well early next morning at 01:30 all power tripped. Load "dwa" and then complete silence. Earth leakage tripped. Switch tank off and got the house power back on. Replace extension plug one by one until I found the extension tripping the power again. NOTE, I did not dare to touch any water, I knew something was wrong. Once the extension was identified it was easy to find the guilty piece of equipment. It was one of the Boyu powerheads. Removed it, and everything returned to normal.

    The Buyo powerhead cord became hard in the saltwater. With the cleaning the previous day the outer plastic cracked at the place it enters the housing, most likely exposing the wires underneath . It took a few hours before the inner wires leaked and actually shorted. It is a 2 wire cord on those pumps.

    Without the grounding probe, I would have had another 5 to 6 hours before I got up that a live wire was hanging around in my tank. Basically causing electrolysis releasing all nasty gases and chemical reactions into my tank. And then, when I eventually got to the tank sticking my fingers in to feed them their morning flakes, most likely still be barefoot and half asleep. I would then be zapped completely awake, or dead.

    This is such a simple solution. DO IT.
