Yes, I would definitely have a GFI outlet. I talked to the electrician that was here the other day and he said it'd be almost impossible to do a dedicated circuit without really tearing things up. The area the tank would sit is pretty much dead center of the house, under a second story.He'll be back in about a week and I'll have him see exactly what all is on that circuit. He sounded like there's no way a tank these days would need one with everything so energy efficient and with the leds, and in a newer house. I don't use a heater or chiller. Anyway, I don't know for certain that's correct but I hope so!
I'm glad to hear some confirmation on this being a fairly simple and straightforward project. I'm still contemplating tank sizes.
