CO2 tank is reading one notch above "Refill".

I've got two kegs force carbing for a BBQ on Sat, 3 days away. I have them on 30psi now, will drop to 12 tomorrow.

What do you think? Do I have enough gas to carb and serve? Or should I punt and get the tank swapped?

If it wasn't so hard to fill the tank during the week, I'd just do that.

Is the co2 tank in the fridge or ambient?

I pulled it out of the fridge and let rise to room temp overnight to take the reading. It's back in the fridge.

Tough call. This is why it's a good idea to have a spare tank.

Do you really want to risk running out during the BBQ?

[blorvak]

No, I indeed do not!

I suppose I'll sacrifice lunch to get a fill up tomorrow.

Where's your sense of adventure?

Actually, let me check my finances. Maybe I'll spend lunch buying a new tank!

Do you plan on keeping the gas on both kegs for the remaining 3 days prior to serving? 

[narvin]

They're expensive for what you get, but the adapter + 16 gram CO2 cartridges are good for emergencies and for serving when you travel.

Can't you take off the regulator and weigh the tank, subtract the tare weight and see how much is left?

[duboman]

Swap the tank, regulators at that mark could mean another week or another 12 hours, IME theyre not very precise

Yes, I am.

Now that's quite reasonable. Short on the time needed to disassemble my system, however.

I do have a portable set up for 2.5 gal tanks with a paintball tank, but only one regulator. I suppose if needed to, I could switch between kegs to keep enough pressure for serving.

But I think I'm just going to buy a brand new tank tomorrow for a backup so I can avoid this in the future.

Thanks everyone!

Don't buy a new tank.  Get a used one and save a couple bucks.

You'll swap it out eventually anyway.

When I was first kegging, I went out and bought my brand new shiny CO2 tank.  I brought it in for a refill, and found out NOBODY in the area would refill it, but you could swap it for another one.  Of course, the look on my face when they brought out this nasty looking green paint-peeling monstrosity was priceless.  Next swap was for one that could have been my original.  Now, who cares?  It's just gonna get swapped out anyway.
