I got the tester and my copper reading are at 2 is that good for treating ich and in one month my tank should be ich free and I could add fish right?Running a copper treatment without a good copper test kit (not the API kit) is very tricky. You need to dose based on the tank's actual volume, subtracting tank decoration displacement, etc. Also, if there is any calcium based sand or rock in the tank, that will absorb copper at an unknown rate, and you will need a copper test kit in order to calculate the redosing of the tank to balance that out.
In a pinch, you can do water changes on the treatment tank, dosing the exact amount of copper needed for the volume of water that you just changed.
The fish should be in the coppersafe treatment for one month.
