It was on a non GFI Tony. This time, as I was moving stuff back to the 90g when it zonked my head. Thats also why my ground probe was out. No voltage with the probe in. On the cube, the Tunze was plugged in the same place, {see below for why}, and my ground probe was not installed yet, for whatever reason. And its a good thing I dont have any hair there, as it likely would have ignited .
I have to measure the Hydor again to see.
So here the thing. I have always kept one pump isolated from GFI plugs, as a last resort to circulate the tank. Plus I have two different GFI circuits on my tank. I picked the Tunze because its the best quality pump I have and figured the last one to leak. As much as I need heat, I wont use a heater non GFI or any of my cheaper equipment.
My halides are on the GFI only circuit as they trip the arc fault breaker on the other one. I,m going to now purchase a 3rd. GFI and have everything on one but three different circuits.
Perhaps just something with my particular Tunze. I still have complete faith in them and with the new motor, hope to run it another 5-10 yrs.
