Aquarium DIY CO2 Generator System Kit CO2 Generator System with Bubble Counter & Check Valve Carbon Dioxide Reactor Kit for Plants Aquarium -rate of CO2 gas indication device and water back into bottle. Be made of aluminum alloy. It is strong, durable and efficient. Professional pressure guage for pressure watching. Cheap, simple to create pure CO2 constantly by chemical reactions. package does not contain solenoid valve andbottles. Equipped with a safety valve, pressure is greater than 4kg pressure will automatically, carbonated beverage bottle pressure is 8kg, safety is ensured. Any problem, please our store without hesitation. to serve you! Well- caps and pipes, leak-proof, non-deformed, never loose. safety valve supports manual pressure . When pressure is below 4kg, it can be manually relieved by pull ring of safety valve. It is very . 3. Don't open bottle directly when there's still on pressure, please wait for its automatic pressure release. Specification: Name: DIY CO2 generator system A bottle: Citric acid 200g+water 600g 3 type optional: CO2 generator system/CO2 generator system+bubble counter with check valve/CO2 generator system+bubble counter with check valve+solenoid Main color: Silver B bottle: Baking soda 200g+water 200g Main material: Aluminum alloy material ratio Note: Package Information: Gift Box Packaging Package size: 22 * 12 * 6cm Package weight: 361g 1. package does not contain containers for reaction materials. Please prepare 2* 1.5L or large beverage bottles (coke bottles are best). Do not use bottles or beer bottles to bottle accidentally cracking or exploding due to excessive pressure in bottle. Package List: 1* CO2 generator system 1* Manual 1* Safety valve 2* Suction cup 1* 1.5m tube 1* Pressure gauge 1* Bubble counter with check valve 1* Fine adjusting valve 2. Boost pressure operation: If pressure gauge shows that pressure is too low to reach 1KG, boost pressure operation is required. Customer needs to open trim valve to release gas, then close trim valve and shake bottle ( AB bottle is shaken together) on order to react materials faster. Repeat operation, and then observe pressure until pressure rising. If pressure achieve ideal pressure you could stop operation. best starting pressure is 1KG. Just add citric acid, baking soda, water into bottle, can produce carbon dioxide. plant metabolic rate can be increased quickly, create best growing conditions for fishes. It is best choice of making CO2 equipment at home. It is easy, and economical. material ratio A bottle: Citric acid 200g+water 600g; B bottle: Baking soda 200g+water 200g.
