2.5lb Tank - Big Enough?

[bearduncle]

I recently acquired a 2.5lb CO2 tank on the cheap. I'd like to keg half of my beer in a 2.5 gal. soda corny and bottle the rest. Is a 2.5 too small? I'm brewing about two 5 gallon batches a month. How often will I have to refill the tank, roughly?

The 2.5 gallon CO2 tank will work just fine for you. I have a 5# tank and have carbonated at least 8 batches and still have some CO2 left. The 2.5# tank will last you quite awhile.

If you decide to upgrade to a bigger tank later, you can use the 2.5# for portable dispensing.

Excellent! Maybe I can mount it to my framepack... camping with a keg!

I had a 2.5# tank I used as a hot spare. I recently took it and my 5# tank to my local AirGas dealer and he wouldn't touch the 2.5# tank - so I annoyed him until he gave me a even trade for another 5# tank. heh

 

[bearduncle]

Why do you think they didn't accept the 2.5#er??

He was just lazy - said it had something to do with the high pressure required to fill such a small tank. I've had it filled elsewhere with no issue, but AirGas has since bought the other company out and I now have no choice...
