OK, thanks. If I do another test in a few weeks and am still getting 1 gpg hardness, what do I do to bring this to 0? If I understand correctly, the salt dose will not fix it, this only determines how many days I can go before I need to regenerate? For the time being, I have it programmed to what dittohead posted, and following the changes I did a manual regeneration. If realistic, I would like to bring the dose lower than the 8 lbs that he posted, but if not then it will be fine. Its really not that big of a difference but if I can save 20-30 bucks or so per year then why not.
