Measuring records as the CPO Ans✓✓✓ 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 Ans✓✓✓ pH, Total Alkalinity, Calcium
Hardness, Temperature, and total dissolved liquids
, Corrosive water Ans✓✓✓ pH is too low, dissolves everything it
contacts
scaling water Ans✓✓✓ pH it too high, mineral deposits on walls or
pipes
Regulated pH range Ans✓✓✓ 7.2-7.8
pH reading is tested with Phenol Red
To lower pH, Ans✓✓✓ add muriatic acid
To raise the pH, Ans✓✓✓ add sodium carbonate (Soda Ash)
2. sodium bisulfate
3. carbon dioxide
Total Alkalinity Ans✓✓✓ 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 Ans✓✓✓ low alkalinity
Regulated Total Alkalinity range Ans✓✓✓ 60-180 ppm ideal goal is
