Assuming you have a 3 wire cable coming in and a 3 wire cable going out, you would want to disconnect both from the outlet and use a wire nut to secure the 2 blacks together, the 2 whites together, and the 2 greens together. Then you will need to pull a new cable from your breaker box to the outlet you want separated.I want to have the duplex on its own circuit
Any good small inverters? Just to turn the 12v into 120v"What about an air bubbler?"
It would work, but how about this?

Cant be beat for a road trip...
Ok what would the setup look like for this? I have a mega I could use, I probably have a relay laying around somewhere as well.Your probably using the wrong type of mosfet (P channel, you need N). According to how this guy has done it you should have 12 volts on the drain all the time, then when you fire the gate from the optical sensor current will flow.
Your gate should have 0 volts on it when the sensor is in the water, 5v out of water.
Overview,
Out of water.
Pump point of sale (+12v)
Pump Neg(+0v)
Fet Drain(2) (+0V)
Fet Gate (1) (+5V)
Fet Source(3) (0V)
In water.

My recommendation would be to use a small micro controller instead (arduino or the like)
Hook the optical sensor up to that and use a relay.
That way you can do things like max run time, contact debounce, alarm, etc.
This setup a very good way to flood your house / wreck your tank.

I also was wondering why you think that this would be an issue. I know that there isn't much controllability to it, but I want to understand from your point of view please
