Where do you fill CO2?
 

I ordered a 5lb tank, and I'll need to get it filled. Where do you go to fill your tanks? Preferably in Newton/Needham area.

I'm not sure if its different for a plant system, but, almost any paintball shop has a co2 filling station. Usually there prices are reasonable. I am not sure if they will fill a large cylinder like that though.

All my co2 is made by yeast. But, I fill my paintball gun canisters at the local Wal-mart for pretty cheap. There's a sporting section in the back, might not be the same for all Wal-marts.

You could try going to a gun hobby store, they usually have paintball refilling tanks. Paintball shooting ranges usually have refilling stations that you can go to and fill free of charge. ;)

Of course you would need to pay for rental or admission, but usually I just walk right in and fill up my tanks and leave.

Hi,
just found this thread...
I have not been in a while, but I have my tanks filled at Igo's Welding Supply in Watertown. A lot cheaper than Airgas for example...

Yup, that's where I've been going. :)
