4. no pool operator (15 minute grace period)
5. no lifeguard or cpr certs present
6. water is below the skimmer line
7. danger to the public
8. chlorinator is not working
9. health inspector is not allowed in

Measuring records as the CPO - correct 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 2 years at the pool and 3 years total.
5 Factors of Water Balance - correct answer ✅pH, Total Alkalinity, Calcium Hardness, Temperature, and total dissolved liquids
scaling water - correct answer ✅pH it too high, mineral deposits on walls or pipes
Regulated pH range - correct answer ✅7.2-7.8
pH reading is tested with Phenol Red
To lower pH, - correct answer ✅add muriatic acid
To raise the pH, - correct answer ✅add sodium carbonate (Soda Ash)
2. sodium bisulfate
3. carbon dioxide
Total Alkalinity - correct 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 - correct answer ✅low alkalinity
Regulated Total Alkalinity range - correct answer ✅60-180 ppm ideal goal is 100ppm
To lower Total Alkalinity, - correct answer ✅add muriatic acid
To raise Total Alkalinity, - correct answer ✅add Baking Soda
Calcium Hardness - correct answer ✅amount of calcium and magnesium in the water (mineral content in water)
Regulated calcium hardness range - correct answer ✅150-400ppm
To raise Calcium Hardness, - correct answer ✅add calcium chloride
Total Dissolved Liquids (TDS) - correct answer ✅sum of all organic and inorganic materials dissolved in the water- cannot be eliminated with a chemical----- <1500 ppm allowed in water
Temperature - correct answer ✅Max temps = 88 for swimming pool
96 for therapy pool
104 for hot tub [Show Less]
