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

Dave harley Garcia
30l nano tank with some fishes,loaches, amano shrimps, and snails

It's doing great so far but I had to put lots of oxygen to balance the o2 and co2 at night to keep the inhabitants safe.
I really hope to see more upgrade in the future, like: a way to turn it off at night.
5 stars!

System set up

Generator works fine - producing abundant plant growth
I use distilled water - warm it a little first, it makes dissolving the citric acid much easier
You can buy bulk food-grade citric acid very cheaply from health food shops or home-brewing shops, and bulk bicarbonate soda from pool shops. Costs virtually nothing to run

Funktioniert aber....

Leider ist die Dichtung am Überdruckventil nicht dicht oder die Feder im Ventil nicht stark genug. Ich habe mich erstmal mit Teflonband (Dichtband) beholfen weiss aber nicht ob das Ventil noch ordnungsgemäß funktioniert. Aber er läuft jetzt. Darum nur drei Sterne.
