Certified Pool Operator Test Review Questions
and Answers| Latest Update
Total Alkalinity 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 low alkalinity
Regulated Total Alkalinity range 60-180 ppm ideal goal is 100ppm
To lower Total Alkalinity, add muriatic acid
To raise Total Alkalinity, add Baking Soda
Calcium Hardness amount of calcium and magnesium in the water (mineral content in
water)
Regulated calcium hardness range 150-400ppm
To raise Calcium Hardness, add calcium chloride
Total Dissolved Liquids (TDS) sum of all organic and inorganic materials dissolved in the
water- cannot be eliminated with a chemical----- <1500 ppm allowed in water
, Temperature Max temps = 88 for swimming pool
96 for therapy pool
104 for hot tub
Saturation Index -.5-.5
check once a week for a pool, everyday for a spa
Employees have the right to know: - may come into contact w/blood
-may come into contact w/ dangerous chemicals
- personal protection
- material safety data sheet
Cyanuric Acid (CYA) chemical used to stabilize an outdoor pool (not UV light sensitive)
added directly through the skimmer,
Regulated Cya levels 30-100 ppm
Sodium Hypochlorite NaOCl Liquid Chlorine, or bleach
Chlorine Breakdown
FAC's and CAC's Free Available Chlorine = good chlorine (disinfects)
