Optimal Swimming Pool Chemical Ranges for Pools
Keep your pool’s chemical readings in these ranges:
- PH: 7.2 to 7.8 (I generally keep it in the middle 7.5)
- Alkalinity: 80 to 120 ppm
- Calcium Hardness: 250-450 ppm
- Cyanuric Acid or Sun block: 30-50 ppm
- Chorine residual: 1.0 to 3.0 ppm
- Combined chlorine: 0 ppm. By managing pool chemistry right, you will substantially reduce the amount of chlorine needed. Much of it is wasted.
