Regulate CO2 flow to aquarium CO2 systems without breaking your budget. Azoo CO2 Pressure Regulator w/Solenoid is priced right for use with freshwater-planted aquariums, calcium reactors for reef aquariums or any setup requiring precise control of CO2. Precision needle valve and 110V electrical solenoid valve lets you regulate the flow from the CO2 tank to your aquarium CO2 system with ease. Blow-off valve allows manual release of built up pressure, and easy-read gauges tell how much pressure is flowing from the CO2 tank to the aquarium and how much CO2 is left to dispense.
