Who has a grounding probe in their tank?

Is it your sump or main tank and is it a good idea to have one?

I have one in the sump, don't know if it makes a difference but I can say I get no tinglies when I have my hands in the tank

I have one in the display herbie overflow and one in my frag tank. I highly recommend it.

Thanks for the input , i honestly didnt even know of such a thing, i will definatly get one. I was just thinking today with all the cords running into the tank and sump there must be something a guy can do.

I've one in my sump as well. I was mildly electrocuted twice before I figured it out and bought one.
