Sad Story: I was on vacation and had someone watching my tank. They didn't notice any problem with shocks, but a circuit breaker kept tripping which turned off everything in the tank. The tank was in my office at work and everyone thought it was just something else tripping the breaker so they kept resetting it. This went on for a couple days before stuff started dying in the tank and I got the email saying something was wrong. By the time I got back to the office, everything, I mean everything, was dead. I couldn't believe it.
The only thing I could do was take the tank down to start over. While tearing things apart I found one power head with a broken wire right at the base as it entered the pump. The poor buggers got the electric chair.
I was pretty bummed and it took two years before I dared start the tank up again. I still worry every time I'm on vacation.
This makes me wonder if a GFCI power strip or even a GFCI breaker would keep this from happening. Anybody have experience with them and know how they would handle a bad heater, pump, etc.?
