What is Neo CO2?

Neo CO2 is a combinational item designed to supply natural CO2 from stablized metabolism of a bacteria called Saccharomyces Cerevisae into aquarium.

How does Neo CO2 Works?

Neo CO2 helps grow aquatic plants by continuously supplying CO2 which is essential for growth at the lowest cost. Neo CO2 supplies CO2 stably for about 50 days (depends on climate)

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.

Features of Neo CO2


Neo CO2 is fermented only on the side jelly and water contact, which makes proper amount of co2 production last longer as the micro-organism eats the nutrition jelly from the upside to the downside.

Stabilization technology for bacteria and special culture material 

Thanks to AQUARIO Co.’s high technology, Neo CO2 developed/introduced stabilize bacteria technology, keeps Co2 production about 50 days.


Neo CO2 reproduces CO2, if only the jelly is still left with a simple process.

Perfect components

Neo CO2 contains all parts necessary for co2 generation and use such as hose and diffuser

World's best diffuser

How to use

  1. Put about 300ml of warm water (about 50℃) into the bottle.

  3. 24 hours later, it turns into Jelly
  4. Put in 1 pack of Biorefill.
  5. Put 200ml of warm water (about 30℃)
  6. Wait until CO2 is produced.
  7. When co2 stops, only the water needs to be changed except the jelly.
  8. Process #4, #5, #6 comes along later on

Recommended for aquariums up to 60cm.


  1. Never disconnect the hose or open the cap before CO2 is generated. This significantly delays or disables co2 generation.
  2. Never shake after the content has turned into jelly.
  3. Never use any valves to control the amount and time of Co2 generation.
  4. The quantity of Co2 decreases slowly as time passes
  5. The result of normal fermentation, Liquid on top of jelly smells of soiled wine.
  6. Below 15℃, Co2 cannot be produced
  7. When the hose or diffuser stuck with the contents by the user's carelessness, please stop using and carefully open the cap in somewhere like bathroom. And connect the syringe to the hose and remove the contents. After that, immerse it in the bleach diluent.
  8. Keep out of reach of children and pet.
