【How-to】How much does it cost to fill a 5 lb co2 tank

A 5-lb CO2 tank will last between 6-8 half barrel, or full kegs, before it will need to be filled. A 10-lb CO2 tank will dispense between 10-13 full kegs per fill. This number can be higher or lower based on how often you’re using your kegerator, the level of carbonation, and if your system is properly balanced.
