Our carbon dioxide aluminum tanks have been used for years in many applications from aquarium uses, hydroponic plant growing and home brewing, beer making.
Why do we suggest the largest size co2 tank that will fit in the space you are going to use it?
1. Co2 of the tank. Prices of tanks are not much different
2. Cost of refills. When refillling a canister it is almost as expensive to fill a 2.5 lb as a 5 lb canister so you might as well get the one that is going to last you 2 x as long.
3. Aluminum so much lighter than Steel so this is much easier to easy to transport.
4. All with new hydro test dates
