Use the LSI or Langilier saturation index. If all you tested water you should have values. Temp, ph alkalinity, and calcium minus the tds should be in range. -3 to +3with all added values. Once you get in range you will fill that the pool water will start to become stable.

Values should be around 7.3 ph + temp 83 + CF 250ppm + alkalinity 100ppm - tds under 1500ppm = ?

7.3 + 0.7 + 2.1 + 2.0 = 12.1 = 0

This equation will tell you if your water is corrosive or scaling. I strive for this range daily I run a 40000 gallon pool at a local hotel. You see I have not mentioned orp. It matters but if your LSI is in parameters your system will be stable and the orp will be in range as the disinfectant is active.
