Where are local places to get a co2 tank?

I don't know where to look locally for a co2 tank. Can I go to smart and final, home depot, lowes? 20lb aluminum tank.

thanks

Welder supplys, usually industrial places like that...When at LOWS ask if they sell welders, act ignorant, say you are an artist and need to weld a sculpture , but not familiar with equipment, soon or later the clerk will show you a welder that uses co2, just ask him where to get it...

a paintball store or a beverage store that has fountain drink parts should carry them

Paintball store --> paintball best game ever... play it in ur weed trees !!!! fuckin heaven

u can get small paintball c02 tanks .. there like a foot long and 3-4 inches wide? like 20oz ? i think ? or u could prolly get the big ones they use to refill those...which are like 4 ft tall like giant scuba tanks.....

Go to welding supply store the will either rent them or sell them. Hydro shops have them. I just sold 1 of my 20 lbs tanks and my 10 lb tank have 1 left if you cant find one.$80 plus shipping

What is the name of the adapter that is needed to convert the paintball gun's pin valve into a regular size co2 tank valve ? I am try ing to hook up my paintball gun tank up to one of those hydrofarm co2 injection regulators

Ok, so let me make sure I have this straight.....

Use Co2 when you are somewhat air locked and use airstones hydroponically?

I'm working on the growin part. LOL
