DIY CO2 System for Aquarium Plants. Aquarium CO2 accessories. DIY CO2 Generator with Pressure Tester and Airflow Control Valve for Plants and Aquariums

Simple operation. Endless DIY fun. Perfect carbon dioxide generator. Includes: 1 x pressure gauge; 2 x bottle caps; 1 x control valve; tubing.

Self-protection design: Prevents water from flowing back into the magnet and cylinder. The aquarium tubing with a backflow function prevents backflow when the pressure changes, which can damage the surface of the aquatic plant and the CO2 cylinder. Smart meter: Used for the CO2 controller. By connecting the water meter, the volume of carbon dioxide can be calculated to provide sufficient carbon dioxide to the plants. It also has a check valve function to prevent liquid from flowing back when the pressure changes. Easy to install and use: A great choice to make your aquarium unique. Simply and inexpensively produce CO2 continuously through a chemical reaction; you only need to adjust the airflow according to the CO2 valve volume.

Instructions: The standard version is a white screw-on bottle cap. The quick-insertion version is a white double-ear quick-release bottle cap. Small U-shaped refiner: The integrated thinning foil top cover design reduces the generation of large bubbles. The large dome is refined, and a bubble memory function is integrated. Four-in-one refiner: Twisted design. Shaping check valve. Bubble function. Hint: 1. Please read the manual carefully before use and use it correctly. 2. The bottle body must be thick. Do not use orange fruit bottles, green tea bottles, or bottles such as mineral water bottles. 3. The fine adjustment valve should not be set too high or low, especially after sudden opening. It should be closed immediately. Fluorescence indicates abnormal pressure that could cause the bottle to burst.
