Yangers aquarium co2 system kit, DIY generator for water plants fish tank, set of tube valve guage bottle cap with needle pressure gauge

DIY CO2 generator system: design a CO2 supply system to help your aquarium plants breathe, which is essential for the growth of your plants. Digital pressure gauge: easy to read pressure gauge display, pressure range 0-6kg/cm². Overpressure protection, once the pressure exceeds the maximum value, the safety valve automatically releases excess pressure until a safety value is reached. Robust design: built-in check valve, bubble counting function. Reduce the generation of large bubbles and increase the refinement area, making the contact area of CO2 and water larger. It is easier to dissolve in water for photosynthesis. Note: Please carefully check the alignment of the parts before assembly. Incorrect assembly leads to abnormal reaction components. The raw material for generating CO2 is not included.
