Description
xSmart CO2 delivery for aquariums
Designed for reliable CO2 management in planted tanks and reef-inspired setups, the FZONE Pro Series regulator helps maintain steady pressure as your cylinder gas level changes. This stability reduces fluctuation in CO2 availability and supports a calmer daily operation without sudden surges.
Key capabilities include an adjustable output that ranges from 0 to 65 psi, letting you tailor CO2 delivery to the size of your tank and the growth stage of your plants.
- Dual stage construction maintains stable output pressure regardless of remaining CO2 in the cylinder
- Adjustable output from 0 to 65 psi for diverse tanks and plant demands
- End of tank transition is mitigated by staged regulation, reducing surprises
Modular two tank ready design
Two independent manifold blocks offer flexible operation. Each block carries its own high precision needle valve and can run on its own, letting you run one aquarium or two with a single regulator system.
- Two independent manifolds each with a precision needle valve
- Use one block for a single aquarium or both for separate tanks
- Includes the necessary installation tools and CGA320 adapter compatibility for North American cylinders
Safety, precision and ease of use
Safety is built in with a valve that opens automatically if pressure climbs beyond 100 psi, helping prevent overpressure events. The integrated needle valve lets you fine tune CO2 output with fine steps, down to one bubble every three seconds.
- Overpressure protection via automatic safety valve
- Precise control down to one bubble every 3 seconds
- Bubble counter helps monitor CO2 flow in real time
Efficient, quiet DC solenoid and NA cylinder compatibility
Operating on 12 volt DC makes the solenoid stable, energy efficient, and quiet. The unit is designed to work with automatic timers and is safe to touch during routine adjustments. North American cylinders with CGA320 adapters are supported, and installation tools are included for a straightforward setup.
