2. pH

3. Calcium Hardness [ppm]

4. Free Chlorine [ppm] & Combined Chlorine [ppm]

5. Total Dissolved Solids (TDS) [ppm]

6. Iron (Must test to a lower detectable limit of <=0.05 ppm)

7. Manganese (Must test to a lower detectable limit of <=0.01 ppm)

8. Copper (Must test to a lower detectable limit of <=0.1 ppm)

B. The following are ideal ranges for the water analysis test results. If results fall outside these ranges the Contractor shall make chemical adjustments to the water during the pool filling process until values within the ideal ranges are obtained.

1. Total Alkalinity: 80-100 ppm (for high pH disinfectants) 100-120 ppm (for low pH disinfectants)

3. Calcium Hardness: 200-400 ppm (Pools), 150-250 ppm (Spas)

4. Free Chlorine: 2.0-4.0 ppm & Combined Chlorine: 0.0-0.2 ppm

5. Total Dissolved Solids: Acceptable Start-up Range is not applicable (Maintain future TDS levels to within 1200 ppm above the start-up measurement)

LSI Equation:

(pH) + (Temperature ºF) + (Calcium Hardness) + [(Total Alkalinity) – (CYA correction factor @ current pH)] – (TDS factor) = LSI
