The Aquario NEO CO2 Diffusor U Type is an acrylic CO2 Diffusor. The special ceramic membrane produces a fine mist and the CO2 gets dissolved very quickly. Perfect for small and nano tanks.

If the lower part is completely filled with water, the bubbles can also be counted directly in the diffuser without any problems.


Before use, immerse the diffuser in water for 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 of the diffuser 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 on our community page Flowgrow.de under Glaswaren reinigen leicht gemacht

Best CO2 diffuser you can buy!

AQUARIO - Neo CO2 Diffusor - U Type - Large

Simple the best there is on the market in terms of price/value! The acrylic material makes it very robust and not as fragile compaired to glass diffusers. Must have!

One of best diffusors I ever tried.

Producing very small bubbles, its cheap and reliable.

And its easy to clean too. Highly recommended stuff.
