I have had the current CO2 cylinder on my tank for just about 3 months now; I will be going on vacation in a few weeks and I'm wondering whether or not I can bring the cylinder in to be filled up before I leave, even though it is not empty yet?
I would hate to have it run out while I'm away but also, it would be nice to know if it's possible to have a cylinder filled before it runs out or if I have to wait until it is totally empty.
Thanks!
