• Complement to CO2 kits or CO2/PH controllers: solenoid valve to dose the supply of CO2 to aquariums
• Simple use: Insertion of the solenoid valve in the CO2 transport hose of the fertilization system or assembly directly on the CO2 regulator of JBL.
• Targeted CO2 supply: adjustment of CO2 supply by activation of a timer or by CO2/PH controller (timer and controller are not provided).
• Unscreased and economical: 12V safety transformer, low heat clearance (absorbed power: 0.8 W), saves up to 50 % CO2, no noise production, universal electronic power supply.
• Contents: 1 silent solenoid valve with tightening nuts pipe and universal power supply block

Why do we need a solenoid valve or a night cut?
As plants only need CO2 for photosynthesis during the lighting phase, you can stop the CO2 intake at night. To avoid the opening and closing of the CO2 bottle, there are solenoid valves (JBL Proflora CO2 Valve) which can be controlled by a timer. In the morning, this timer highlights the light and the contribution of CO2 via the solenoid valve and in the evening, it turns off the two. Intelligent aquariophiles immediately recognize that the expense of a solenoid valve is quickly amortized because it saves 50 % of CO2. It is always installed between the regulator and the anti -return valve or we screw it directly on the regulator. If you want to use a pH controller with automatic CO2 regulation, you will also need a solenoid valve. It will then not be started by the timer, but through the PH controller (JBL Proflora Co2 Control).

High danger and economical
with a consumption of 0.8 W, the valve body becomes barely hot and works with 12 V safety transformer. The magnet is silent and saves up to 50 % of CO2 since the contribution of CO2 is interrupted at night.
