ZISS CO2 Air Diffuser
ZISS CO2 Air Diffuser
Comes with two pads and can handle both CO2 (carbon dioxide) and Air supplies.
Both pads has indefinite performance life and does not require replacement.
Foam of the pad is finer than other similar products and creates excellent dissolution rate.
How to use: At the time of purchase, a white pad is set for adding CO2. Replace the pad according to your purpose. When using for air addition with Air, replace the white pad with the green pad. Even if the air pad (green) is used for CO2, sufficiently fine bubbles will be generated. Tightening the cap with a tool may cause damage. Try tightening it by hand to avoid injury, and then use a tool if necessary. When using for the first time, please note that the foam is rough for the first 30 minutes because the pad is not compatible with water. After that, it gradually becomes finer.
