These components help automate calcium supplementation. Combine with Hydor Perfomer CR Calcium Reactors to make reactor CO2 ready. Pinpoint pH Controller monitors pH level in upper and lower ranges and cycles solenoid valve on or off accordingly to adjust pH readings. Features easy-to-read large LCD and includes a probe and calibration fluids. 9V battery required (sold separately). CO2 Pressure Regulator with 110V electrical solenoid valve works in conjunction with the pH controller for precise flow of CO2 from CO2 tank to calcium reactor. Blow-off valve allows manual release of built-up pressure, and easy-read gauges tell how much pressure is flowing from the CO2 tank as well as how much CO2 is left.
Includes: pH Controller, CO2 Pressure Regulator with Solenoid, and 20 ft kink-resistant Silicone Tubing. CO2 bottle not included.
