Will these CO2 tanks work for my application?

Where do you live ? LOL The only place in the State of Kentucky that does that process of switching tanks is Wal-Mart and K-Mart hehe. All local Hardware stores are glad to fill my tanks. Mostly free just because I buy stuff from there stores often. Plus the tanks should last like I said 4-6 weeks with a bypass valve to split the two tanks. As long as I know it can work thats all I wanted to know. I just need a regulator and a diffuser with piping.
 
I bought my equipment at Scott-Gross, but I think I'm going to have my tank filled at AirGas as well - I'm not too keen about having my shiny new aluminum cylinder exchanged...:(

My cylinder is still going strong though, but that was the first thing I checked was refilling after I bought the cylinder - Turns out that AirGas is close to my home and I'll be going there.
