calcium reactor co2 bottle question

[uncleant]

I am looking into a calcium reactor and just have a few questions. I have a 125 display with a 55 gal fudge/sump. Where can i purchase a co2 cylinder or bottle? How big of one do i need? And how fast do they run out? Thank you all very much

How fast the bottles last depend on how much CO2 you're using. It's not unheard of to get a few months out of a 5lb bottle. You can pick up a bottle online, or you can look and see if you can't rent one at a restaurant supply place. The bottles they use for carbonated beverages are the same thing.

Check with fire extiguisher places too. Co2 is Co2.

Welding supply houses are also a good source.
