Horrible air efficiency!?!?!?!?

Hi. I just got my new fly and i have a 45ci nitro duck 4500psi tank. I aired it up and shot about 50 shots and my tank was empty. I have my volumiser on. Can anyone help me?

Sounds like a shocker. :)
On a more serious note, it wasn't leaking or anything? Might be the tank. I would check the tank first.
