Default CO2 Tanks Size Recommendation?

I have a 5# CO2 tank I currently use for 2 kegs in a fridge. I will be building a keezer very soon. At the moment I am thinking of 4-5 kegs on tap with the potential of 1-2 (right now my plans are for a 6-keg keezer) carbing. I will keep the tank outside the keezer. What size tank is recommended from you experience?

I'll keep the 5# charged for backup when the other tank needs refilling.

I have a few 20lb tanks and one 40. You cant go wrong with a 20lb....but YMMV.

If you're keeping it outside the fridge, go for the biggest one you can, probably a 20#. Less fills and cheaper $/lb when you do fill.

Another vote for the 20lber. It is really, really sad if you get a leak and drain your tank (only happened once, but it really rather sucks as I live 2.5 hrs from a co2 swapper) but unless that happen they last just about forever.

I ferment/crash cool in a barn and dispense in my garage so I actually just use the 20lb tank to force carb in the barn and then dispense with the 5lber which tucks nicely onto the hump in my keezer.

I use a 20# to carb my beers (warm), and I have a 10# in my 4 tap keezer. Being that is used just to "push" beer and not carbonate, it lasts me over a year between fills.

That's the first thing I thought of was losing 20lb of CO2 would really suck.

I have a 10# for force carbing and 2-5# for the keezers. That way if I get a leak I'm only out 5# of CO2. Even the 5# last a long time.

Compare prices between 5 pound setups and 20 pound setups. You get four times the gas for only twice the price with a 20 pound setup.

And when you go to refill you pay pretty close to the same amount for 5 pounds of gas and 20 pounds of gas, so...why not go for the 20 pounder?

Swapping tanks is a funny thing. It's not so much the cost of the gas, but the tank fee's. It cost 20$ to swap a ten pounder and 24$ to swap a twenty pounder. A better example, is O2, 10cf and 125cf both cost 20$ to swap at Airgas.
