Aquarium

In order to control the supply of CO2 to the aquarium, a solenoid valve is used in combination with a timer. The valve stops the supply of CO2 during the night, because plants only absorb CO2 during daytime. This reduces the overall CO2 consumption, which results in substantial cost savings. The solenoid valves are available with different voltages and can be equipped with fittings for different pipe diameters.
