About this item
- Expandable Dual stage for Multiple Aquariums: This CO2 Regulator aquarium kit includes two bubble counters with quick-connect fittings, allowing easy setup for up to two tanks. The modular design lets you expand to more aquariums if needed, making it ideal for multi-tank setups. Simply plug in the tubing without disassembly—no tools required for hassle-free operation.
- Dual Stage Adjustable Pressure & CO2 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.
- Big dual gauge design, sturdy and durable: Our upgraded CO2 regulator is constructed from hard aluminum alloy, making it rust-resistant, durable, and ideal for long time 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.
- Reliable Sealing and After-Sales Support: Using professional sealing technology, this CO2 regulator prevents leaks for safe, worry-free use. Backed by a 2-year warranty and responsive customer service, we ensure your satisfaction. Includes all necessary accessories for easy installation with W21.8 CO2 tanks, perfect for establishing a reliable aquarium co2 system.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
