About this item

• For first-time use, after setting the automatic mode, if the system is running, please switch to manual mode to turn it off first, then turn it back on. After turning it on, switch back to automatic mode to activate the built-in program and ensure proper operation. Just follow the above steps to set it up once, and you can use it normally afterwards. We are currently optimizing and adapting the timer’s built-in program for future direct use.Thanks for your understand and support!
• Things to Note Before Purchase --(1)The motorized valve may make a soft sound when turning on/off — this is normal; (2)Soak the diffuser in your aquarium for 24 hours before use. If bubbles aren't released right away, wait briefly due to low initial air pressure. If problems continue, check tube connections for leaks; (3)The motorized valve is not waterproof; (4) Baking soda and citric acid need to be purchased separately.
• Revolutionary Motor Valve Technology -- Upgrade your aquarium setup with our advanced CO2 generator system featuring a state-of-the-art motor valve. Unlike traditional solenoid valves, our motor valve allows you to set precise timers, ensuring consistent CO2 injection at your desired intervals. This exclusive feature sets our CO2 system apart from competitors, providing unparalleled control for optimal plant growth.
• Quick-Release Structure for Hassle-Free Installation -- Experience the convenience of our CO2 aquarium kit's quick-release design. The bubble counter, valve, and air tube all feature a snap-in structure, replacing the old screw-on design. Installation and disassembly are now a breeze, saving you time and effort.
• Heavy-Duty & Durable Build -- Our 2L CO2 bottles are crafted from 1.2mm premium SUS304 stainless steel, while the 5L ones are made of 1.5mm premium SUS304 stainless steel, both being 20% thicker than standard tanks. These robust bottles are far superior to plastic alternatives, offering enhanced durability, stability, safety, and high-pressure resistance, ensuring long-lasting performance.
• Comprehensive Safety Features -- Your safety is our priority. An automatic pressure relief valve activates when CO2 pressure exceeds 30-40bar, safeguarding your aquarium from overpressure risks. With careful design and quality materials, we've minimized potential leakage points, ensuring a secure operation environment for your aquarium and its inhabitants.
• All-In-One DIY Kit -- Our CO2 generator for aquarium plants comes as a complete kit. It includes a CO2 cylinder, hose, suction cups, bubble counter, CO2 diffuser, and the innovative motor valve. Simply add baking soda, citric acid, and water to the cylinder, close the valve, connect the accessories, and start providing your aquatic plants with the CO2 they need.
