The Chihiros CO2 diffuser is suitable for aquariums from 50 - over 200 l. The special ceramic membrane ensures a very fine atomisation of the CO2 bubbles. The small CO2 bubbles are easily carried along by the water flow and distribute themselves very efficiently throughout the aquarium.

If the diffuser is filled with water, the individual rising CO2 bubbles can be counted without any problems.
The diffusers are made of robust acrylic and are easy to clean.


  • Discreet CO2 diffuser for nano aquariums and bigger tanks
  • Available in 4 variants for aquariums from under 50 to over 200 l
  • Particularly efficient atomisation by means of special membrane
  • Good readability of the CO2 bubbles in the body of the diffuser


Before starting up, soak the diffuser in water for about 10 minutes so that all the air in the diffuser is displaced. If there is still air in the diffuser, larger bubbles may form at the bottom edge of the diffuser ceramic.

When algae start forming on your PETG equipment or when larger and larger bubbles emerge from your ceramic diffusor it is time for cleaning. PETG-ware is easy to clean, however, it should be done diligently. After the cleaning process, your PETG products will be as good as new.

  • You'll need a household bleach containing chlorine without perfumes. When working with chlorine bleach, please make sure you absolutely observe the manufacturer's safety notes.
  • Pour some of the bleach into a container and mix with an equal amount of water. Mix so much of this solution that the PETG products you wish to clean are entirely covered
  • Soak the PETG-ware in the solution for ½ - 1 hours (depending on the severity of the stains)
  • Take it out and rinse thoroughly
  • Now all the stains ought to be gone, and your PETG-ware should shine as if new
  • Attention: Do not add vinegar to chlorine! Risk of death!

You'll find an extensive how-to (in German) with pictures in our Aquascaping Wiki under Glaswaren reinigen.
