The AQUARIO NEO CO2 Diffusor Curved Special is an acrylic CO2 Diffusor that brings the features of the NEO Special Type and upgrades them with yet another smart attribute. It is equipped with a very narrow diffusor body and the connection to the pipe at its side. This special small design ensures a fine integration of the diffusor into small and nano tanks.

Example Layout

The particular ceramic membrane produces a fine mist and the CO2 gets dissolved very quickly.

Moreover, this diffusor has curved tube ends which make it easy to hang the diffuser over the edge of the tank so that unattractive hoses do not disturb the eye anymore.


For finest bubbles it is advisable to put the diffusor into water for 10 minutes, so that all membrane pores get soked completely. If the bubbles get bigger with time, you can clean the membrane with bleach. You will find a detailed describtion below.

When algae start forming on your acrylic diffusor or the emerging bubbles become larger and larger it is time for a thorough cleaning. Cleaning is easy, but should be done diligently. After the cleaning process, your CO2 diffusor 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 diffusor you wish to clean is entirely covered
  • Soak the acrylic CO2 diffusor 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 diffusor should shine as if new

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