Note: Because Scaltrol neutralizes minerals, rather than removing them, your readings before and after installing a Scaltrol will be the same.  This does not mean the Scaltrol isn't working - it is doing exactly what it should. If you want more information on how the Scaltrol works, see our Frequently Asked Questions.
