Who has a grounding probe in their tank?

[heyfredyourhat]

There is a decent size thread about ground probes being very dangerous on RC.

My 2 cents...I have one in my sump, i have a gfi as well. The other nite hands were in the tank and i got a good jolt and then gfi tripped. It was my light, and about a year ago i was shocked by the same light and didnt have a gfi installed. Talk about being electrocuted!! Especially when one arm is all the way to the bottom of a 24" tank!!!

Not sure what the ground probe does, or if its worthwhile, but i know i love my gfi now!!
