[TRIX]

Man that sucks. My theory....... If you have your heaters in your sump and have a grounding probe close by the electricity should go almost directly to the grounding probe. So none of the electricity should make it's way into the display tank thus reducing a killer jolt to any livestock. Now if you don't have a sump I would put the probe as close as I could to the most concentration of electrical things in the tank. This is just my thoughts. But man don't give up. Take this oportunity to make any changes you've always wanted to and start again.
