5 lb. Aluminum CO2 Cylinder with CGA 320 Valve

Beautiful shiny finish, easily operated valve, a quality cylinder that seems well made. I got to admire it until I took it to get it filled at my local welding supply store, where they let me know that they do cylinder exchanges and I won't get mine back. Fortunately, they had a cylinder to swap that look ALMOST as good as the new shiny one I gave them. Don't get attached to your cylinder because you probably won't ever see it again once you exchange it.

i needed a CO2 tank for my aquarium, every where i checked the tanks were $100 or more, i saw this one i think with delivery was around $75. the tank is brand new in perfect condition. took it to get it filled (yes it is shipped empty which it needs to be shipped empty) the tech who filled the tank was impressed with its look this thing is quality even the valve handel is made of metal. i expect many years of use with this tank. if you need a CO2 tank for your aquarium i highly recommend this tank. it looks sharp with a brushed aluminum enterer.

Great purchase.no leaks. Lasts a long time. Adjustments are precise.

When you go to Air Gas to fill this you don't get to keep your bottle They give you credit for the one you bought, but they don't fill them there, so you get a prefilled one every time you need a refill. The swap out a pre filled tank. So I would recommend not buying a bottle. I got credit for my new bottle but will never see it again! Sad to say. Had I known this I would not have wasted time on the whole thing.

Got this for my aqua scape came in perfect condition and Airgas in Wisconsin had no issues exchanging tanks. Bummed I got a not so good looking tank in exchange but moral of the story buying from here and taking this tank in saved me $40

Solid cylinder but a lot of companies have gone to an exchange system. Most will not fill on demand, but within a few days time.

Perfect cylinder to buy just to swap out for a full one at your local welding supply for planted aquarium!

I bought this to save money on sodatream. I bought one of the adapters and connected to this tank. It's perfect! I used to pay 15.00 for the exchange and that lasted muy family about two weeks, sometimes less. This lasted us two and a half months on one fill! Costs about 16.00 to fill where I get it done(my local brewery store) For the cost of one of the sodastream, i can go about five times longer.
