Description
The CO2 gas is atomized into many bubbles by the diffuser. The bubbles create a larger contact surface enabling the CO2 to dissolve quickly in the aquarium water.
The bubble counter visually controls the dosing of the CO2. As a rough rule of thumb: approx. 20 mg CO2 per litre. This corresponds to about 10 bubbles per minute per 100 litres of water.
