The CO2 diffusor from Twinstar is made out of acryl and is, therefore, not prone to breakage. The diffusors function extremely efficiently because their special membrane technology allows a very fine CO2 atomisation. The membrane is not located inside the diffuser, as is usually the case, but on top of its body. The advantage is that the CO2 bubbles are able to stream out of all the membrane's pores, on top as well as on its sides. Hereby, the diffusor provides the best possible carbon fertilisation in a planted aquarium.

In addition, they are equipped with clear suction cups and fit all commercially available 4/6 mm CO2 tubes.


  • Made of acryl, less fragile than glass
  • With a high-quality ceramic membrane
  • Very fine CO2 atomisation
  • Suitable for standard 4/6 mm hose
  • Transparent suction cup included


Before use, immerse the diffusor in water for 10 minutes so that all the air in the diffusor is displaced. If there is still air in the diffusor, larger bubbles may form at the bottom of the diffusor ceramic.

When algae start forming on your glassware equipment or when larger and larger bubbles emerge from your ceramic diffusor it is time for cleaning. Glassware is easy to clean, however, it should be done diligently. After the cleaning process, your glassware 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 glassware products you wish to clean are entirely covered
  • Soak the glassware in the solution for 1 to 4 hours (depending on the severity of the stains)
  • Take it out and rinse thoroughly
  • Now all the stains ought to be gone, and your glassware should shine as if new

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