Give your planted tank precise, reliable CO2 control. The Fzone Pro Series Regulator pairs a built-in safety valve (releasing pressure above 100 PSI) with an integrated needle valve for fine-tuned output down to just one bubble every 3 seconds — perfect for dialing in the exact CO2 levels your aquascape needs.
 
A newer 12V DC split-type solenoid runs quieter, cooler, and more efficiently than older 120V AC models, and works seamlessly with automatic timers for hands-off dosing. The large 1.6" dual gauges make it easy to monitor both cylinder and working pressure at a glance, while upgraded sealing materials help prevent leaks over time.
 
Designed for North American CO2 cylinders with a CGA320 fitting; all installation tools are included.
