The bubble counter is used to detect the amount of CO2 that is released into the aquarium.
The bubble counter must be filled with 2/3 aquarium water, in order to achieve a good function (control).
The arrow on the bubble counter shows the direction of the administered CO2. This arrow always points in the direction of the Ceramic Diffuser.
Caution : because the bubble counter is made of glass, you have to be very careful during its assembly.
The set-up of the CO2 tube happens with lukewarm water en must be carried out very carefully, as to avoid breaking the glass.
