Aquario Neo CO2 Refill

The Aquario Neo CO2 Refill provides a simple and cost-effective way to maintain stable CO2 levels in your aquarium, supporting healthy plant growth.

How to Use

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

2. Close the cap and shake the bottle about 100 times until the contents are thoroughly mixed.

3. After 24 hours, the mixture will turn into jelly.

4. Add 1 pack of Biorefill.

5. Pour 200ml of warm water (≈30℃) into the bottle.

6. Wait until CO2 is produced.

7. When CO2 stops, only the water needs to be changed—the jelly can remain for the next cycle.
