EHEIM CO2 diffuser 400l

CO2 Filter

The CO2 gas is converted into many bubbles by the filter. The bubbles create a larger contact surface, enabling CO2 to dissolve quickly in the aquarium water.

The bubble counter allows visual control of the CO2 dosage. As a rough guideline: approximately 20 mg of CO2 per liter. This is equivalent to about 10 bubbles per minute for every 100 liters of water.
