Efficient enrichment of the aquarium water with CO2:
Inside the diffuser is a special diaphragm through which the CO2 diffuses into the aquarium water, which is pumped back into the aquarium by the external filter. The very small CO2 bubbles dissolve very well in the water and save about 20 % compared to other CO2 diffusers.
Replacing the diaphragm
Due to sedimentation from the aquarium water, the efficiency of the diaphragm decreases over time. For this reason we recommend an annual replacement.
