High-Efficiency CO₂ Supply System: FZONE CO₂ generator system uses a citric acid and sodium bicarbonate reaction to produce high-purity CO₂, delivering stable pressure and flow through a CO₂ regulator, bubble counter, and CO₂ diffuser. Unlike traditional cylinder systems, it requires no refilling at CO₂ stations, making it more convenient.
Enhanced Safety Design: The FZONE aquarium CO₂ system is made from food-grade 304 stainless steel with body 50% thicker for greater strength and pressure resistance. The CO₂ system includes a manual shut-off valve for safe control when CO₂ is not needed, and an automatic pressure-relief valve that releases excess pressure when it rises above the safe limit,providing dual safety protection for worry-free operation.
Precise and Reliable CO₂ Control:The FZONE CO₂ generator for plants use a precision needle valve for smooth, accurate flow adjustment. The bubble counter provides a clear view of CO₂ injection rate, while the pressure gauge displays real-time tank pressure. Its upgraded all-in-one solenoid minimizes connections and leak risks, ensuring stable, consistent CO₂ delivery for your planted aquarium.
Ready to Use: This complete aquarium CO₂ kit is designed for easy setup and convenience. It includes all essential accessories CO2 diffuser, check valve, U-connector, suction cups, tubing, funnel, syringe, sealing rings, and power adapter — no extra parts required.
