Fzone CO2 Regulator

The Fzone CO2 Regulator provides dual-stage pressure regulation and a built-in solenoid at an accessible price point, making it an attractive entry-level option for hobbyists moving from bio-CO2 to a pressurized system. Dual gauges display cylinder pressure and working output pressure, enabling straightforward monitoring of cylinder level and flow rate. The integrated solenoid is compatible with standard aquarium timers, allowing day/night CO2 automation to reduce consumption and protect livestock during dark periods. An integrated bubble counter eliminates the need for a separate unit and allows easy visual monitoring of CO2 flow rate. Compatible with standard CGA320 CO2 cylinders, the Fzone regulator suits tanks of all sizes and pairs well with any ceramic or glass diffuser.
