Testing Pool Water

These are the chemical levels recommended for most swimming pools (always consult a professional for
recommendations for your specific pool)
pH: 7.2 - 7.8
Chlorine: 1.0 - 2.0 ppm
Total Alkalinity: 80 - 120 ppm
Calcium Hardness: 180 - 220 ppm, though some say 200 - 400.
Cyanic Acid: 25 - 50 ppm
Total Dissolved Solids: 500 - 5000 ppm

Once a week the swimming pool water needs to be tested for chemical balance.  pH and Chlorine levels need to be
checked and corrected regularly. Other chemicals needed to be tested less frequently.
