I am converting an old mini fridge into a kegorator and want to put 2 5 gallon kegs inside. What is the recomended size of co2 tank to run 2 kegs?

i would say a 5 pounder would be great. you could use paintball tanks but unless you have a few already it would be easier and cheaper to get a 5. I have a 5 pounder running 3 kegs now and I have carbonated and served 7 kegs so far but I know its about to run out.

I run two kegs with a 5lb tank. If you don't have leaks you can get 8 to 10 legs out of the tank.

I run 2 five gallon cornies on a 5# tank. I'm on my fourth keg and should be able to push the rest of these 2 out before I need to refill. I also use it to carb as well as push. If you naturally carb you would probably be able to push 10-15.

I can't speak to Recommendations, but I run a two faucet, two keg system off of (what I think is a) 5# CO2 tank with no noticeable problems.

I use a 10 lb tank for 3 taps, carbonating and serving. If you can handle the size, 10 lbs is great! Here's the best place to buy any size CO2 tanks... get the reconditioned ones since most places just trade out anyway:

I run 4 taps on a 2.5 lbs. tank. I also have a 5 lbs. tank, but it doesn't fit in my fridge as well. I carb off a 20 lbs.

You could use a 5 lb tank and get several kegs out of it, but I would recommend going with a 10 or even a 15 just to have extra gas.

get whatever you can find for cheep! I have (2) 40lb tanks and am going on 2 years on the current one. The cost for larger tanks isn't much a step up. I'd get as big as you have space for. Now of course the larger they are, the more expensive leaks are. So check your system!
