I have a titanium grounding probe that I always placed in my sump. Seeing as I am rebooting my 125 gal, I am wondering where everyone places their probes. My reasoning for placing the grounding probe in the sump is my hands are mostly in the sump during maintenance and so long as the main pump is pumping to the DT I will receive the benefit of having my DT grounded as well. What are your thoughts on this and where do you place your grounding probe and more importantly your reasoning?
