Ziss CO2 ZC-II is the completely new patented carbon dioxide generator by chemical neutralization. CO2 generation speed can be controlled by the speed control valve. The innovative pressure equivalent design can give safe and constant CO2 supply to the plant tank. Because ZC-II works by chemical neutralization, high purity CO2 can be generated instantly and CO2 generation is not affected by the temperature.
If you use our Ziss ZCR-160 generation kit, the amount of CO2 generation is around 160g, which can be used around 45days in the around 100 Liter tank.


Don't forget to add your generation kit: ZCR-160

Pablo Mauricio
Very Good Quality CO2 Generator

It works great the translation of the instructions in English are a little off but if you read it carefully you'll be fine. I wish I could buy it on USA because it took 2 weeks to get here from the Netherlands, overall is a good product and if you do some research online you'll fin some people that already tried it and will help you with the settings and will give you some tips to successfully set it up. A tip from the vendor please right correctly the address were it would be delivered since mine was take it back to the postal office because of a error on my address made by Ziss Aqua people. Also when submitting the review it says that I can add up to 5 pictures but is not possible, there is no button or link to add them. :/
