Enhance your aquatic environment with this DIY CO2 Generator System, expertly crafted from durable aluminum alloy for long-lasting performance and efficiency. Designed to produce a steady flow of pure carbon dioxide through safe and simple chemical reactions, this system is ideal for boosting plant growth and creating optimal conditions for fish in your aquarium. Key Features: · **Durable Aluminum Alloy Construction:** The main components are made of high-quality aluminum alloy, offering strength, corrosion resistance, and efficient operation for prolonged use. · **Leak-Proof, Well-Sealed Design:** Equipped with tightly sealed caps and pipes to prevent leaks, deformation, or loosening, ensuring reliable and safe CO2 generation. · **Professional Pressure Gauge:** Accurately monitor system pressure with the integrated pressure gauge, enabling precise control to maintain ideal CO2 levels. · **Safety Valve with Automatic Pressure Relief:** The built-in safety valve automatically releases gas when pressure exceeds 4kg, protecting your system from overpressure. It supports manual pressure relief by pulling the ring when pressure is below 4kg for enhanced safety. · **Bubble Counter with Check Valve:** Allows you to visually track the CO2 flow rate while preventing water from flowing back into the system, ensuring consistent and safe operation. · **Economical and Easy CO2 Production:** Uses simple chemical reactions by adding citric acid, baking soda, and water to create pure CO2 continuously, making it a cost-effective solution for home aquariums. · **Comprehensive Kit with Accessories:** Includes pressure gauge, safety valve, fine adjusting valve, bubble counter with check valve, 1.5m tubing, suction cups, and a detailed manual for convenient installation and use. Specifications: · Material: Aluminum Alloy · Color: Silver · Product Type: DIY CO2 Generator System · Optional Configurations: CO2 generator system / CO2 generator system + bubble counter with check valve / CO2 generator system + bubble counter with check valve + solenoid (solenoid and bottles not included) · Raw Material Ratio:  - Bottle A: Citric acid 200g + water 600g  - Bottle B: Baking soda 200g + water 200g Important Notes: · Reaction containers are not included; prepare two 1.5L (or larger) plastic beverage bottles (preferably soda bottles) for chemical reactions. Do not use glass or beer bottles to avoid risk of bursting under pressure. · To boost pressure if below 1kg, release gas with the trim valve, then shake both bottles to accelerate the reaction until the ideal pressure (around 1kg) is reached. · Never open the bottles while pressurized; wait for the system to automatically release excess pressure before handling.
