Any electricians in the house?

Could just get a second PH and put a NC relay between it and the Elimanator. Use the utility power to hold the relay open.

Relay could have a 12V coil supplied by a small AC plugin wall adapter.

So then I would have a powerhead in the tank that is not running UNTIL the power goes? Is that right?

Yes.

If going the other way ensure you get a 'break before make' contactor.

I would prefer to go the other way. What is a 'break before make' contactor? and how does it work?

In the link a 'breaker before make' is described. Essential as could be making smoke without one.

Thanks, I will have to figure out exactly what I need so I can build it over the holidays.

I was wondering if it is possible to just use my existing UPS backup system (designed for computers) except I would disconnect the wires going to the little UPS battery (12v) and hook them up directly to the battery in the Motormaster Eliminator.

Basically I am just utilizing a larger battery for my UPS and bypassing all the inverter & charging systems built into the Eliminator power box.
