Rehash;
My tank runs on a separate 15 amp circuit, installed just for it, with a GRI outlet in the wall. My controller, which runs the lights, heater, return pump, skimmer, reactor, and top off all runs from it.
Another room receptacle, which is on another 15 amp, but room circuit and has an Arc fault/ GFI breaker, runs my two MP 20,s, plus another in tank heater if we are away.
