- Factors of Water Balance - ANSWER pH, Total Alkalinity, Calcium
Measuring records as the CPO - ANSWER Operator must test the water for Cl and pH every hour, and Total Alkalinity, Calcium Hardness and Cyanuric Acid once per week. Records must be maintained on site and available for at least
Hardness, Temperature, and total dissolved liquids Corrosive water - ANSWER pH is too low, dissolves everything it contacts 1 / 2
scaling water - ANSWER pH it too high, mineral deposits on walls or pipes Regulated pH range - ANSWER 7.2-7.8 pH reading is tested with Phenol Red To lower pH, - ANSWER add muriatic acid To raise the pH, - ANSWER add sodium carbonate (Soda Ash)
- sodium bisulfate
- carbon dioxide
- / 2
Total Alkalinity - ANSWER represents the amount of carbonates, bicarbonates, and hydroxides in a solution - you want this to be high, because the pH resists changes in fluctuating pH Bounce - ANSWER low alkalinity Regulated Total Alkalinity range - ANSWER 60-180 ppm ideal goal is 100ppm
