CO2 fertiliser system with automatic CO2/pH control to supply all aquarium plants in freshwater aquariums from 40 to 600 l ideally. CO2 cylinder (disposable or refillable) and factory-fresh pH electrode to be purchased separately Simple assembly: screw pressure reducer onto CO2 cylinder (not included), connect solenoid valve to CO2 control unit, hose to bubble counter/check valve and reactor. Attach pH electrode (not included). Set CO2/pH control unit No hose slippage thanks to hose screw connections, check valve prevents water from entering the cylinder. Pressure gauges show cylinder and working pressure. Pressure reducer fits disposable and refillable CO2 cylinders The CO2/pH Control unit measures the pH value (CO2-dependent) via the pH electrode (not included) and automatically regulates the CO2 supply via the solenoid valve until the ideal pH value with the correct amount of CO2 is reached Package contents: pressure reducer with solenoid valve, CO2/pH computer, 3 m hose, bubble counter with check valve, TAIFUN SPIRAL CO2 reactor + extension set
