This system actually has patented technology that allows for predictable CO2 usage. When sized right, refills are extremely infrequent - as little as once a swim season or even less. The manufacturer site gives pretty detailed information about CO2 use, you can see that here: https://www.circupool.com/CircuPool-TOTALBalance-pH-Control-Acid-Free_p_158.htm
