Compatible with all US standard CGA320 CO cylinders no extra purchases needed, plug-and-play setup right out of the box.
• Precision Regulation Stable CO Output. High-sensitivity pressure gauge clearly displays cylinder pressure (up to 2000 psi) and output pressure simultaneously. Precision diaphragm regulator ensures consistent, stable CO output flow no sudden surges or pressure drops, keeping your aquatic plants in an optimal growing environment around the clock.
• Tool-Free CGA320 Installation with Self-Sealing Quick-Connect Directly fits US standard CGA320 CO cylinder threads. Self-sealing design prevents gas leakage during installation no tools required. Quick-connect fitting allows one-second connect and disconnect for easy cylinder swaps and maintenance.
• Micro-Adjustment Needle Valve Precise to 1 Bubble per 8 Seconds. Integrated precision needle valve with graduated dial knob enables ultra-fine flow control. Adjust CO bubble rate accurately down to 1 bubble per 8 seconds perfect for nano tanks and small aquariums that demand exact dosing.
• Smart Solenoid Valve The solenoid valve allows automatic on/off timing control (timer sold separately) turns on during the day and off at night. The diffuser produces ultra-fine bubbles for optimal dissolution efficiency. The water-refill bubble counter provides a clear visual indication of the flow rate, while the built-in check valve prevents water backflow from damaging the regulator.
