I know the answer is "It depends", but how long does a 5 lb CO2 canister last you on average?When I took my rig to the golf course for the charity tournament someone moved it without asking me and they dropped the gas on the pressure gauge on the end. Not the end of the world, they are cheap and can be replaced. I tried to replace it two nights ago and I can't get the ####ing thing threaded. I think the one I bought is threaded the opposite way, which is strange because its supposed to be exactly the same as the one on the reg. So I am guessing at how much gas I have left now until I can fix this stupid thing. I have only used it to carbonate 3 kegs so far and have had some noob losses as well.Cheers,Rich

Yeah, really hard to say. I have three 5lb tanks. 2 of them are split between my 4 kegs and I have another one that I use for carbonating. So 2 of them sit at 8-10 psi all the time (when one goes, I use the backup tank in the serving fridge and refill the empty tank which then becomes my carbing tank) and the other one is used to seal & carbonate kegs. I wish I could say for sure, but I would guess that I go to the gas-refilling-type-person 4 times a year. Ish.

Funny thing is that it will look like it is fine for the longest time, but when it decides to drop to empty, it does it almost immediately. I keep a second tank on hand for just such occasions.

Volumes of CO2 * 2 = grams per literSo figure out how many volumes of CO2 you carbonated each keg with, multiply by 38 (19 liters * 2) and that's how many grams you used. Then convert to pounds and sum the 3 kegs together. Subtract that from 5 and you'll get what is left in the tank, approximately of course.

Yeah, some are "RHT" right hand thread and some are LHT. It should say on the gauge.

There should be a tare weight stamped on the tank. Remove the reg and weigh it - anything over tare is CO2. Here's a link too, I think that is for steel tanks.https://www.beverage...Tank FAQs.shtmlNot dumb, I was asking this last year.

[chuck_d]

Oh yeah, tare weight, much better approach :)I just went with the standard answer I use for "how many kegs are in a tank?"

Admit it Chuck, you were just showing off! Haven't seen you around much. What's new?

[chuck_d]

Haha, I have too many formulas in my head... I must admit that the tare weight is a much more elegant and accurate solution to knowing how much is left.Right now I'm trying to learn how one finds commercial space in New York. A totally new process to me... anyone know how to find warehouse space in the city?

PM me... I may know someone who knows someone who knows someone. Just need a few details as to size, location, purpose and budget.

Nice Chuck!Just from our short conversation I can tell you have a passion for beer, and the knowledge to make something great! I'm thinking NY would be happy to receive some of your brews!

The short answer is that 5lb of CO2 will carbonate 138 gallons of beer to 2.2 volumes, theoretically.
