It is a used tank that has been fixed or had parts replaced.
No paintball gun will work without a CO2 tank or other propellant tank. without Co2 there is nothing to push the ball out of the barrel.
A CO2 tank does not necessarily have to be upright. It depends if you want liquid CO2 or gaseous CO2. When I purchased a CO2 tank for a specific application, namely, CO2 snow cleaning, I had the option of getting a tank that either had a dipstick, that picked up liquid CO2 from the bottom of the tank, or one that had no dipstick so that it collected gas from the top of the tank. I selected a tank without the liquid pickup. So, my upright tank output gas. However, if I wanted liquid CO2, I would put my tank slightly upside down, and get liquid CO2. It is probably not recommended to run a commercial gas tank in a non-upright position. So, depending on what type of tank you have, and what type of output you want, the answer to your question literally is: depends. For farm and garden use, you are probably seeking gaseous output, and probably have a tank with no dipstick; based on these assumptions, yes, you will need to keep your tank upright.
No co2 tanks are sold full.
"H" is not a size for CO2 tanks
There is no such thing as a "CA" tank.
You cannot unless you have a gauge installed, or know the exact weight of the tank.
yes you can when you use a compressor only fill up the co2 tank for 2 seconds for every ounce the tank can hold (9 ounce tank=18 seconds) <><><><><> However, the CO2 tank is designed for CO2, not ordinary air, and it is rated for only a specific pressure. If you don't have the proper equipment to do this, it is better for your own safety to leave it to a professional.
1 pound of co2 = 7 cubic feet in its gaseous state
A carbon dioxide tank must contain only CO2.But many mixtures of gases containing CO2 may be prepared.

Yes, a jockey box typically requires a CO2 tank if it is being used for serving carbonated beverages, such as beer. The CO2 tank provides the necessary pressure to push the beer through the lines and into the serving tap, ensuring it remains carbonated. If the jockey box is used for non-carbonated beverages, a CO2 tank would not be needed.
There is not a place where you can trade in Co2 tanks. Except possibly a pawn shop.
