Aquacontroller III Pro

I was wondering if it were possible to control equipment based on the Conductivity readings coming from the probe. I was thinking of a three solenoid system for topoff. The first is controlled by the float switch. I will call this the control solenoid. I guess technically before this would be two more solenoids, One that lets RO water through and the other that lets saltwater mixed at 1.030.

I wanted to see if it were possible to say that whenever the conductivity probe measured an amount less than the equivalent of 1.026 then open the solenoid of the salt water container. Then when top off is needed the control solenoid opens and salt water is added until topped off.

Then if the probe reades the equivalent of 1.026 or above fresh RO water is added as top off. In this way it is possible to make up for both loss of salt through skimate, creep, spills, etc. and make up fresh water lost through evaporation.

Conductivity changes with temperature so you'd have to factor that into the equation as well.
