not sure what method you ae using but connect the Solenoid valve to a pH controller and place the pH probe into the calcium reactor. The set point valve 6.5 to 6.7. then switches the CO2 on and off to maintain a target pH within the reactor to then the other side probe pH probe is placed in the tank, and switches on the CO2 flow to the calcium reactor only when the pH in the tank has dropped too low like 7.9 or 8.0 then that kicks the reactor back on I have never messed with a Coralife unit so I'm not totally sure about your set up.. If you can post the PH controller unit and model maybe I or someone can tell you more about the way it works I am assuming you use a solenoid valve on the CO'2 tank ?
