About This

• Please note: The thread specifications of this product are designed for standard CGA320 gas cylinders, and the power adapter supports 110–240V. This product is primarily intended for U.S. customers. If you are outside the United States, please check whether the thread specifications and power adapter are compatible with your local setup.
• Expandable Manifold Design for Multiple Tanks: This complete CO2 regulator kit includes two bubble counters right out of the box, enabling simultaneous CO2 supply to two aquariums. Its innovative quick-connect fittings allow you to insert tubing directly—no disassembly or tools required, making setup effortless. The expandable manifold design allows you to easily add more outlets in the future, making it the ideal, scalable solution for multi-tank setups.
• Dual Stage Adjustable Pressure & Flow Control:Our upgraded CO2 regulator features a dual-stage pressure regulation structure to ensure more stable output pressure. The main valve adjusts the output pressure, while the integrated needle valve allows for precise control of gas flow rate. This provides consistent CO2 delivery for your aquarium plants, maintaining optimal levels in your planted tank.
• Motorized Valve with Timer for Automatic Control: The advanced motorized valve, paired with a timer, enables fully automatic CO2 control on your set schedule. Unlike old solenoid valves that heat up during continuous operation, our motorized valve only activates during opening and closing, preventing overheating and ensuring energy efficiency for long-term reliability.PSThe solenoid follows your preset schedule, not the power state. Even after a power outage, CO2 will resume and continue running for the remainder of the set time window.​ Set a daily runtime limit for automatic shutoff and fish safety.
• Dual gauge design, sturdy and durableOur upgraded CO2 regulator is constructed from hard aluminum alloy, making it rust-resistant, durable, and ideal for long-term use. The clear dual-gauge design allows for precise monitoring of both cylinder and output pressure. It features a quick-connect bubble counter with a built-in check valve to prevent water backflow, and a high-precision needle valve that can be fine-tuned to several bubbles per second, delivering the optimal CO2 supply for your aquatic plants.
