pH Controller SMS122 by Milwaukee

Web store price may not reflect retail store price.


pH controller with standard plug socket support, .1 resolution, includes AC adapter. Calcium Reactors require CO2 in order to function properly. This controller will turn OFF the CO2 feeding the reactor when the pH level drops below the desired set point. Plants require CO2 during the day when the lights are on and O2 at night for respiration. The SMS122 pH controller enables you to automate your dosing of CO2 and makes sure that the plants in your aquarium are always healthy. Simply plug in the solenoid valve to the plug socket supplied. Includes pH probe.
