How long does a 500 g filling of a compressed gas cylinder of a ProFlora CO2 system last?
A general answer to this question cannot be given, as that would require additional information such as the number of bubbles per minute, whether you use a night time switch-off and how long the CO2 is supplied each day.
The storage life of a filling can be calculated approximately in a simplified manner. A CO2 bubble contains approx. 0.125 mg CO2, which is for 20 bubbles per minute of withdrawal for 24 hours 3.6 g of carbon dioxide per day or a range of slightly less than 139 days for the 500 g cylinder.
With a night time switch-off and 12 hours of CO2 supply, the range is slightly under 278 days for the same number of bubbles.
The calculation of range is analogous for the 2 kg compressed gas cylinder.
