Ideal Ranges
Free Chlorine | 1.0 – 3.0 ppm |
Combined Chlorine | 0.00 – 0.05 ppm |
Total Chlorine | 1.0 – 3.0 ppm |
**With water purification | 0.6 – 1.0 ppm |
Bromine | 3.0 – 5.0 ppm |
Alkalinity | 80-120 ppm |
pH | 7.2 – 7.8 |
Calcium Hardness | 200–350ppm* |
Stabilizer (Cyanuric Acid) | 30–70ppm |
Salt Level (Zodiac) | 3000 – 3900 ppm |
Copper | 0.00 – 0.03 ppm |
Iron | 0.00 |
*Calcium Levels should be on the higher end in Concrete Pools.
*Calcium Levels should be on the lower end in Salt Pools.

Making Chemical Adjustments
To Increase | To Decrease | |
Chlorine | Unstabilized Granular or Liquid Chlorine | Dilute the pool water Keep the pool surface exposed to allow burn-off |
Alkalinity | Alkajuster | Dilute the pool water |
pH | pH Up | pH Down |
Calcium | HyCal | Dilute the pool water |
Salt | Add Salt | Dilute the pool water |
Copper/Iron | N/A | If Stain Erase does not work: – Dilute the pool water – Stain and Scale Control – Natural Chemistry Products |
Bromine | Bromine T ablets Oxidizer | Dilute the pool water |
When doing a series of adjustments, make sure to adjust pH levels first, then alkalinity.
Always add the chemical to the water, never the water to the chemical!
