I got a new fox face yesterday, he began picking on rocks and algae as soon as he went it the tank. After a couple hours, I couldn't find him. When he came out of hiding, I saw that he was constantly twitching his fins. That brought me to realize that I had some stray voltage in my tank. I figured out that it's my return pump. The pump can be run externally so I was wondering if I pump the pump outside of the sump if that would help with the stray current till I can get a new pump. A grounding probe will take too long to get here but already ordered it.
