It's a 20-ounce CO2 tank made for use with paintball guns. I got that one at Wal-Mart for around $25 and then had to buy a valve and hose for it from a local welding supply company, which is also where I get it refilled at, for $10 per refill.



One tank will last a long time, especially if you put down several rodents/rabbits at a time instead of just one or two. It takes just about as much CO2 to put down 1 rat as it does to put down 30.



I went overboard and got a braided hose but the simple plastic lines/hoses will work just as good if not better. They're more flexible and easier to handle than the braided.



I recommend first finding out where you can get CO2 tanks refilled at (welding supply, sporting goods store that has paintball supplies, etc...) and you should be able to get everything you need from them, all in one stop. Tank, valve, hose and fittings to connect hose to tub or bin, and last but not least, CO2.



Yell if you have any more questions, glad to be able to help. I almost didn't see your post this time because you replied to someone else's post & not mine. I just happened to look further down the posts and saw your reply.



Have a good one!
