CO2 diffuser

Is a carbon dioxide distributor, used to introduce higher CO2 volumes into fresh-water aquariums when little space is available. By means of a universal holding device it is attached directly to the edge of the aquarium and ensures a distribution of up to four CO2 bubbles per second. In the aquarium the diffuser operates as a “stand-alone” solution with a small submerged pump, which draws in the water and thoroughly mixes it with CO2. Dissolved CO2 only leaves the unit; no carbon dioxide is wasted. The diffuser is suitable for aquariums up to 1,000 litres (264 USgal.) of fresh water. 230V/50Hz (115V/60Hz), 5 W, cable 2 m (78.7 in.).

Bad experience with Tunze CO2 diffuser August 17, 2012
Reviewer: Dwayne from GA United States  
I'm sorry to report that this CO2 diffuser did not last for a year on my aquarium.  The initial installation was rather difficult and awkward, and in fact I had to jerry-rig it with rubber bands to keep the clear plastic reaction chamber attached to the pump.  (The water pressure from the pump has a tendency to blow the chamber off).  

Maintenance was also difficult and awkward, and if the water level dropped below the level of the pump, I had to take of the debris filter to manually restart the fan blade.

After several months, the rubber attachment started to erode, giving the clear plastic reaction chamber no purchase, and it simply would not stay on without rubber bands or clips.  

Finally, CO2 bubbles started to escape through the pump unit and now I'm back on the market looking for something more reliable.  

I will state that when it WAS working, it did seem to diffuse CO2 satisfactorily.
