FZONE Aquarium CO2 Regulator Mini Series V3.0 Dual Stage with DC Solenoid and Bubble Counter – CGA320 Compatible

Stable CO2 delivery for vibrant aquariums

The FZONE Aquarium CO2 Regulator Mini Series V3.0 brings a thoughtful blend of precision engineering and practical design to hobbyists who want reliable CO2 support for their tanks. Built with multi‑stage control and a 12V DC solenoid, this regulator aims for steady output and smooth operation, letting you focus on aquascaping and plant health rather than constant readjustment. The compact form and easy tuning make it a versatile option for many setups.

Key benefits at a glance

• Stable output pressure and CO2 flow across a range of cylinder pressures, helping to keep your aquarium consistent.
• Working pressure adjustable from 0 to 60 psi, giving you flexible control as your tank evolves.
• 12V DC solenoid valve for safer, lower-noise operation and reliable actuation.
• High‑precision needle valve for fine tuning, capable of achieving slow, controlled CO2 delivery (about one bubble every three seconds in typical use).
• Bubble counter with a check valve to prevent backflow, making it easier to monitor flow directly at a glance.
• All installation tools included and ready for setup, reducing the guesswork when configuring fresh CO2 lines.

The regulator is crafted from a hard aluminum alloy with a durable finish, and the pressure knob and fine tuning are designed for smooth, repeatable adjustments. Its compact size suits many tanks, and it is compatible with Paintball tanks or any CGA320‑threaded cylinders and 5/8" UNF disposable cartridges. Note that some cartridges with different threads (for example certain Fluval 45g models) may not fit without an adapter. The kit emphasizes safety, stability, and ease of use, making it a practical option for hobbyists exploring CO2 enrichment.

What you get and how it helps

• Bubble counter with check valve helps you read flow directly and protects the bottle from water backflow.
• Included installation tools streamline setup, so you can get your system running with confidence.
• Aluminum body with a durable, spray‑finished surface resists everyday use while maintaining a clean look in your setup.
• Mini size supports almost all tanks, making it a flexible choice for small and mid‑sized aquariums.

Real‑world use often centers on achieving stable CO2 delivery for lush plant growth and clearer water. While results depend on your setup and plant species, this regulator’s design supports careful, gradual adjustments, helping hobbyists explore gradual dosing rather than abrupt changes.
