CO2 Diffuser

The diffuser atomizes CO2 gas into numerous bubbles, which increases the contact area and allows the CO2 to dissolve rapidly in the aquarium water. The integrated bubble counter provides a visual means to monitor CO2 dosing. A general guideline is to aim for approximately 20 mg of CO2 per liter, which translates to about 10 bubbles per minute for every 100 liters of water.
