Sera CO2 Regulator Dual Guage Elevate your planted aquarium with precise CO2 control using our high-quality, dual-stage CO2 regulator. This essential component of any CO2 injection system (CO2 kit) ensures optimal CO2 delivery for thriving aquatic flora. Key Features: Accurate Pressure Control: Fine-tune CO2 injection for your specific aquarium needs, promoting healthy plant growth without harming fish. Dual Gauge Design: Monitor both cylinder pressure and working pressure for safe and efficient CO2 delivery (CO2 setup). Durable Construction: Built to last, this regulator withstands the demands of long-term aquarium use. Easy to Install: Streamlined design simplifies setup and integration with your existing CO2 system components. Please Note: This regulator is a single-stage unit and does not include a solenoid valve (CO2 solenoid). A solenoid valve can be purchased separately for automated CO2 dosing based on your lighting schedule. Sera pressure reducer is required for reducing the pressure within the CO2 bottle (approx. 50 – 60 bar/725 – 871.2 p.s.i.) to a pressure that allows supplying the aquarium (0.1 – 2.5 bar/1.45 – 36.3 p.s.i.). The sera flore CO2 pressure reducer with integrated fine adjustment valve is made in Germany and reliably and safely reduces the gas pressure. It can be connected to all common CO2 bottles with external valve.
