so i recently picked up a 10lbs tank from my local homebrew store, and payed $21 for a fill, only to hook it up and find the next day after carbonating the regulator has dropped to the order soon marking, which stumbled me, because i tested for any leaks before storing it in a cold environment (garage) should i go back and ask them to fill it back up?

you are aware that your tank high pressure gauge is going to drop to ~500 PSI when it is stored below 40df even when it is completely full, right?

this chart is a keeper:

wasn't trying to make you feel dumb - perhaps I should have phrased that a bit better - not my intent.

hey -you didn't know - you asked, and now you do!

one other good thing to do, if you have a scale that will weigh something that heavy is to weigh the bottle after filling (tare weight is required to be printed on the bottle) and then you know how many pounds you got and can keep track of how much is left in it.  also, perhaps weigh it with the regulator attached and then you can keep track of how much CO2 you are using.

Weigh it! (without the regulator)  The tare weight should be on the tank.

Oops - make that +1, what Paul just said!
