Neo CO₂
Product introduction
What is Neo CO2?
Here is the solution to the problem between dangerous high-pressure CO2 and inconvenient low-pressure CO2.
High pressure CO2 is dangerous and expensive.
Low pressure CO2 does not work well to grow aquatic plants.
CO2 is an essential item to grow beautiful aquatic plants.
Don’t worry anymore!
Neo CO2 is the alternative from now on.
Neo CO2 is a combinational item designed to supply natural CO2 from stabilized metabolism of a bacteria called Saccharomyces Cerevisae into aquarium.



How Neo CO2 works?
Neo CO2 helps aquatic plants grow by continuously supplying CO2 which is essential for photosynthesis—at the lowest cost.
The origin of Neo CO2
C6H12O6 → 2C2H5OH + 2CO2 + 2ATP
Neo CO2 supplies CO2 stably for about 50 days.



Scientific Results
Neo CO2 offers the best environment to grow aquatic plants.
Features of Neo CO2
1. Top-fermenting
Only the jelly portion in contact with water ferments, ensuring steady CO₂ generation as microorganisms consume nutrition from top to bottom.
2. Stabilized bacteria & special culture medium
With AQUARIO Co.’s technology, Neo CO₂ maintains stable fermentation for around 50 days.
3. Reusable
If the jelly remains, simply refresh the solution to restart CO₂ production.
4. Perfect components
Includes every part required — hose, bottle, and diffuser.
5. World-class diffuser
Each Neo CO₂ Set includes the original Neo Diffuser, globally acclaimed for quality and fine bubbles.

How to use
- Put about 300ml of warm water (about 50℃) into the bottle.
- After closing the cap, shake about 100 times until the content is thoroughly mixed.
- 24 hours later, it turns into Jelly
- Put in 1 pack of Biorefill.
- Put 200ml of warm water (about 30℃)
- Wait until CO2 is produced.
- When co2 stops, only the water needs to be changed except the jelly.
- Process #4, #5, #6 comes along later on

Cautions
- ※ Never disconnect the hose or open the cap before CO2 is generated. This significantly delays or disables co2 generation.
- ※ Never shake after the content has turned into jelly.
- ※ Never use any valves to control the amount and time of Co2 generation.
- ※ The quantity of Co2 decreases slowly as time passes
- ※ The result of normal fermentation, Liquid on top of jelly smells of soiled wine.
- ※ Below 15℃, Co2 cannot be produced
- ※ 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.
- ※ Keep out of reach of children and pet.
