Neo CO2 s a bio CO2 solution that features a longer reaction time with a more constant CO2 production compared to other CO2 solutions. The sugar resides in a gel that forms inside the bottle, the yeast gradually dissolves the gel and the sugar in it from top to bottom. Depending on the temperature the yeast solution above the gel becomes inactive due to the increasing amount of alcohol after 20-60 days. When that happens the yeast solution simply is exchanged with a new one, the gel can remain in the bottle until it is completely spent. Refill sets including gel and yeast are available.

This set contains the reaction bottle, tubing, gel-powder and several packages of yeast as well as a diffusor with suction cups and a free check valve provided by us.

It takes approx. 24-48 hours till the CO2-production starts.


  • Comes with check valve and diffusor
  • Contains gel-powder for up to 50 days
  • Refill sets are available

I am impressed
2nd November 2017

I followed the instructions very carefully and after nearly a week, no bubbles were produced. I become very annoyed...but, after a few more days suddenly, bubbles! (read more)

Nicht schlecht aber auch nicht gut
3rd May 2016

Grundsätzlich ist das Ganze nicht schlecht. Ich verwende die Bio CO2 Anlage in einem kleinen 10l Cube. (read more)

Um einfach mal einen Einstieg in dieses Bio CO2 zu erhalten ist dieses Set gut zu gebrauchen. Eben als Alternative zum flüssigen CO2 Zusatz. (read more)
