Ziss Aqua CO2 Generator Unit ZC-II
The Ziss CO2 ZC-II is a completely new patented carbon dioxide generator that uses chemical neutralization for CO2 production. The generation speed can be adjusted using the speed control valve.
The innovative pressure equivalent design ensures safe and consistent CO2 supply to the plant tank. Since it operates via chemical neutralization, high-purity CO2 is produced instantly and is not affected by temperature fluctuations.
The ZC-II generator, when paired with the ZCR-160 generation kit, produces approximately 160g of CO2, sufficient for about 45 days in a 100-liter tank.
*** Please note: This is the generator unit only and does not include any reagents. ***
Don’t forget to purchase the ZCR-160 generation kit to complete your system.

FAQ
How does the ZC-II generator produce CO2?
The ZC-II generates CO2 through chemical neutralization, which allows for instant and high-purity CO2 output without being affected by temperature changes.
Can the CO2 output speed be adjusted?
Yes, the CO2 generation speed can be controlled using the built-in speed control valve.
What reagents are required to operate the ZC-II?
The ZC-II unit requires the ZCR-160 generation kit, which contains the necessary reagents for CO2 production. The generator unit itself does not include any reagents.

The ZC-II generator works reliably and maintains a steady CO2 supply. I noticed no fluctuations even during temperature changes. The speed control is easy to adjust. I bought the ZCR-160 kit separately and it fits perfectly. Overall, a solid choice for aquarium setups.
Jessica Butler –
It’s a smooth operation with consistent CO2 output. The setup was straightforward and the generator stayed stable over several weeks. Only downside is that the reagent kit needs to be purchased separately, which I had to do ahead of time.

I’ve used this unit for over a month and it’s performed well. The CO2 level in my tank remains stable, and the system is quiet and efficient. The chemical neutralization method is a big plus for temperature-sensitive environments.
