EHEIM CO2 diffuser 400l

CO2-Diffuser

This diffuser atomizes CO2 gas into numerous tiny bubbles. These bubbles increase the surface area, allowing the CO2 to dissolve swiftly in the aquarium water.

The integrated bubble counter helps monitor the CO2 dosage visually. A general guideline is approximately 20 mg of CO2 per liter, which equates to roughly 10 bubbles per minute for every 100 liters of water.
