Aqua Art CO2 Solenoid Valve

Solenoid valve for carbon dioxide (CO2 ). Regulates the dosage of CO2 into the aquarium. Connected to a timer, it allows CO2 dosing to be turned on during the day (lit aquarium) and turned off at night (darkness in the aquarium). It can also work with a pH controller computer, regulating and maintaining a constant CO2 level in the water. When the CO2 in the cylinder is exhausted, it prevents the reducer and cylinder from being flooded with water.
