2. What five factors are involved in water balance? - Correct Answer: pH,
Total Alkalinity, Calcium Hardness, Temperature, and Total Dissolved Solids.
3. What happens if water balance factors are out of range for too long? -
Correct Answer: It can lead to corrosive or scaling conditions in the pool and
circulation system.
4. What is the pH scale range? - Correct Answer: 0 to 14.
5. What is the pH of distilled water? - Correct Answer: 7.0, which is
neutral.
6. What should be done if the pH is too high? - Correct Answer: Add
Muriatic Acid to lower it.

11.What chemical is used to raise pH levels? - Correct Answer: Sodium
Carbonate (soda ash).
12.What chemical is used to lower pH levels? - Correct Answer: Muriatic
Acid.
13.What is the purpose of a saturation index? - Correct Answer: To
calculate and maintain proper adjustments to swimming pool water.
14.What should be done if the pH reading is outside the ideal range? -
Correct Answer: Adjustments should be made using appropriate chemicals.
,15.What is the effect of corrosive water on pool surfaces? - Correct
Answer: It can dissolve metals and damage plaster surfaces.
16.What can result from scaling water? - Correct Answer: It can lead to
cloudiness, scale, or residue deposits.
17.What must be posted in the guard room? - Correct Answer:
Certifications for SPO, Lifeguard, and CPR.
18.What is the role of in-service training for pool personnel? - Correct
Answer: To ensure staff are trained and compliant with safety protocols.
19.What is the acceptable method for testing pH? - Correct Answer: Using
Phenol Red (R-004) in a comparator tube.
20.What is the consequence of denying a health inspector access to the
facility? - Correct Answer: The pool may be closed by the Health
Department.
21.What is Muriatic Acid used for in pool maintenance? - Correct Answer:
To decrease pH levels.
22.What is the recommended dosage of Muriatic Acid to decrease pH by 0.2
units? - Correct Answer: Approximately 12 oz per 10,000 gallons.
, 23.What is Sodium Bisulfate used for? - Correct Answer: As a dry acid to
lower pH levels.
24.What is the dosage for Sodium Bisulfate to decrease pH by 0.2 units? -
Correct Answer: Approximately 1 lb per 10,000 gallons.
25.How does Carbon Dioxide affect pool alkalinity? - Correct Answer: It
helps maintain alkalinity but can eventually raise total alkalinity outside
recommended ranges.
26.What is the dosage for Sodium Carbonate (Soda Ash) to increase pH by 0.2
units? - Correct Answer: Approximately 6 oz per 10,000 gallons.
27.What chemical causes pH to lower when added to pools? - Correct
Answer: Gas Chlorine (Cl2).
28.What is Total Alkalinity a measure of? - Correct Answer: The number of
carbonates, bicarbonates, and hydroxides in a solution.
29.What is the ideal range for Total Alkalinity in pools? - Correct Answer:
80-120 ppm, with a goal around 100 ppm.
30.What happens if Total Alkalinity is too high? - Correct Answer: It will
resist pH changes and may cause cloudy water.
