Also, dosing is not meant to raise the levels... you need incremental doses for this. A dosing system is to keep it stable. Your dosing should arrest any fall. Then, when you are sure that you have it stable, then add some incremental doses to raise it to where you want it.
Yes, you can lower and raise levels with a doser, but it is not all that easy sometimes.
