works that precisely
The number of bubbles per minute is used to calculate the amount of CO
the aquarium. Thanks to its fully-developed design, the DENNERLE CO
Counter Exact caters for simple and convenient readings: since it is swivel-
mounted, it can be moved into the ideal position. The white reflector bracket
makes it possible to count the bubbles accurately, even in poor lighting con-
ditions, for example, in floor cupboards. Strong hose connectors with coupling
rings provide safety and guard against CO leaks. Thanks to the 3 different
2
fastening options, the bubble counter can be used almost anywhere.
The CO bubbles generated by the DENNERLE CO Bubble Counter Exact
2 2
have an average weight of 0,125 mg and a volume of 0,063 ml. 10 per
minute therefore correspond to a CO supply of 1,8 g or 0,9 liters per day.

DENNERLE Profi-Tip:
• Even when using CO diffusors with built-in bubble counters, it is wise
2
to use an additional bubble counter connected near the pressure redu-
cer, since this makes adjusting the bubble number easier, quicker and
more accurate. In the case of CO diffusors without a built-in bubble
2
counter and those installed in aquariums concealed behind plants and
stones, it is absolutely recommended to use the bubble counter as a
control instrument.
