Who fills CO2 bottles?

[mlm]

I am looking into getting a calcium reactor but before I get it I am wondering who will I get to fill the CO2. What kind of places do you bring your bottles to to get filled?

a welding supply store will usually fill them

I take mine to a fire safety place.

----'s Sporting goods (they might only replace it...not sure if they will fill it) and beer manufacturing company's are good places to call and inquire.

Also paint ball stores have CO2
