3000psi is the capacity of the tank, not the output pressure.
As stated previously, get a ninja tank (4500psi). With a ninja tank, you can adjust the output pressure by removing shims from inside the regulator. That way, you can get the pressure lower and not have issues with the G5.
A standard compressor from a home improvement store will not fill a paintball tank. The output on those compressors is not enough pressure.
