I also plan on using the AQT to control the CA reactor. Rather than set a large range for the on/off pH limits...you should be able to set tighter limits. You should be able to control how often the solenoid cycles by adjusting the bubble count.
The bubble count will control the speed that the solenoid/controller can bring the pH down. If the bubble count is high, the reactor will react rapidly and the controller will shut the CO2 down fast.
The flow through rate will control how fast the pH rises back up again...(as well as the amount of Ca/Alk that you are adding)
You get the bubble count (dropping the pH) equal to the flow through (raising the pH)...and the controller won't do anything...except keep control of the entire situation, which is exactly what we want it to be doing.
