I got it all figured out it took me over an hour, I'll look at the brand of pump tonight and let everyone know but it was a CL special i have had for about 4 years. never had a probelm with it till now. I'm just glad the current was not stronger it may have been a diffrent story. Now where is the best place to order the grounding probe? I'm not messing around with that anymore, way too scary. All my fish were just looking at me like i was doing it on purpose....still don't know for sure if they could feel it but i could. It was about a 12 volt battery shock...not gonna kill you but it hurts a bit. just think i had to unplug each item one by one and put my finger back in the water to test....here was the run down, skimmer, heater, return pump, 4 powere heads, GFO powerhead, UV, fuge power head and last but not lest fuge pump. Of coure it was the last item I tried. We should do a group buy on grounding probes...this scared he heck out of me each time i put my finger in to test i didn't know if the current had gone up....glad it didn't. I'll tell everyone the brand of pump tonight.
