This model fits only Turbo Chalk Reactors made of PVC.
With this control an automatic dosing of CO2 for a Turbo Chalk Reactors is possible. With maximum power the internal pH of the lime reactor is about 5.2 to 5.5 and realizes maximum efficiency. You can upgrade all AquaCare Turbo Chalk Reactors with this control. At starting and if too less CO2 is in the reactor, the control opens the solenoid to let CO2 in. If the right level of CO2 is reached, the control closes the solenoid.
You do not need a pH probe for this control - no calibration necessary.
