At what PH range does high Calcium Hardness become a problem or make the water appear cloudy? If I have more than 300ppm in Calcium Hardness with a PH of 7.2, will the water still appear cloudy? One last question: Does 120 ppm or 250 ppm of Calcium Hardness, 80 ppm of Total Alkalinity, 50 ppm of Borates, and a PH of 7.2 cause any problems to the pool water?
How does "Hard Water" compare to "Soft Water" is there a difference to how one feels in the water? Isn't "Soft Water" corrosive in some way, which irritates the skin? Does "Hard Water" irritate the skin as well?
My goal is to find the right the saturation equation for my pool, which does not cloud the water nor make it corrosive in any way.
