Pat, I have very little scaling now--less since the swg was installed (not what I expected, but it's great!). My TA is only 90 according to the PS233. My system is well-balanced except for the Ca level and that is the same as last fall when I closed. The cell on my Clearwater is clear so I visibly check it often and I did do a muriatic acid soak on it at the beginning of this spring. Why would the salt level change "while removing scale?" I had to adjust my salt level this spring because we got soaked this winter in California and my water was very diluted, but now we won't see rain until next fall so the salt level should be fixed.

Doesn't the salt water test use silver, which is expensive? That's probably why they don't have too many in stock.
