I use a 12 ounce, it lasts me a full day, but you might need a bigger one (20 ounce) if you shoot a lot of balls (eg. automatic firing) Tanks are a lot of preference but largely the 20oz is the standard co2 tank that will offer on a typical entry level setup about 1500 shots. For HPA whatever size you get, get it in a 4500 psi tank, that way you will get more shots out of the same size tank. The 68/4500psi has largely become standard for HPA tanks and will give you around 1300 shots on an entry level setup
The sizes 9 oz and all the way up to 20 oz can be used for paintball gun. Some of the paintball guns are supposed to be used by the larger tanks. So the size of tank depends on your paintball gun.
Yes, you can use any size tank
Yes, every few games, you will have to refill the tank, depending on the size. Without it, there is nothing to propel the paintball.
A compressed C02 tank or High Pressure Air tank propels the paintball.
3-6 pounds for a 98 Custom depending on the tank size
Where the air tank or co2 tank normally attaches
size is all personal preference, you can get something as small as a 9oz or up to a 24oz co2 tank, the larger the tank is the more shots you will get off of it but the heavier and larger it will be
your local paintball field. Or you can purchase a scuba tank and adapter to fill the paintball tank with and every once in a while fill the scuba tank up if you live like out in the middle of nowhere
that depends on the size and pressure of the tank, ninja makes everything from 12ci tanks to i believe 88ci tanks. which tank are you looking at?
Take it to an airsmith or paintball tech.
it would be unwise to have paintball loaded and the gas tank in. If would give the wrong impression if cops stopped you. But there are no laws stating you can't, as long as you are over 18.
No.
