I live in Cape Coral, Fl and have extremely hard well water. I have an oversized water softener and was considering using softened water for the auto top off. I listed the test results of my water below. Based on those results, what would you recommend? I'm not exactly sure how CH is added or removed from the pool... Does an in ground concrete pool with a Pebble Tec finish actually absorb CH?
It appears that if I use well water that I may end up with excessive CH and scale. If I use softened water I will have to add CH but I'm not sure how much or how often.
Calcium Carbonate (CaCO3). I believe this is what you pool guys call CH but I'm not positive.
46 grains per gallon or 786.6 ppm
Calcium Carbonate (CaCO3).
<1 grain per gallon or <17.1 ppm
