rate can be increased quickly, create the best growing conditions for fishes. It is the best choice for making CO2 equipment at home. It is easy, safe, and economical. Raw material ratio: A bottle: Citric acid 200g+water 600g; B bottle: Baking soda 200g+water 200g.

Specification:
Name: DIY CO2 generator system
Main material: Aluminum alloy
Main color: Silver
Voltage: AC 100V-240V input; DC 12V output
Raw material ratio:
A bottle: Citric acid 200g+water 600g
B bottle: Baking soda 200g+water 200g

Note:
1. The package does not contain containers for reaction raw materials. Please prepare 2* 1.5L or large plastic beverage bottles (coke plastic bottles are the best). Do not use bottles or beer bottles to avoid bottles accidentally cracking or exploding due to excessive pressure in the bottle.
2. Boost pressure operation: If the pressure gauge shows that the pressure is too low to reach 1KG, the boost pressure operation is required. The customer needs to open the trim valve to release the gas, then close the trim valve and shake the bottle (the AB bottle is shaken together) in order to reach the raw materials faster. Repeat the operation, and then observe the pressure until the pressure rising. If the pressure achieves the ideal pressure you could stop the operation. The best starting pressure is 1KG.
3. Don't open the bottle directly when there's still on pressure, please wait for its automatic pressure release.
