My water also comes out of my well at around neutral, but with 260 ppm, not good. As THG said, most systems require less than neutral water and it flucuates immensly if your ppm's are wack. I use distilled for now that is about .9 ppm and very easy to control PH level's. But it sounds like you have it all figured out, good luck!!
