What should be added to pool water when calcium hardness is too low (below 150 ppm)?
Answer: Calcium chloride
Calcium chloride is added to pool water to raise calcium hardness and prevent the water from becoming corrosive to pool surfaces and equipment.
What is 'shocking' a pool?
Answer: Adding a large dose of oxidizer or chlorine to break down combined chlorine and contaminants
Shocking involves adding a high concentration of chlorine or non-chlorine oxidizer to destroy combined chlorine, algae, and organic contaminants.
At what approximate water temperature does algae growth in pools become significantly more likely?
Answer: Above 60°F (15.5°C)
Algae growth accelerates significantly above 60°F and becomes aggressive above 80°F, requiring more diligent chlorination in warm conditions.
What does 'combined chlorine' (chloramines) refer to in pool water testing?
Answer: Chlorine that has bonded with nitrogen waste compounds and is no longer effective as a sanitizer
Combined chlorine consists of chloramines formed when free chlorine reacts with ammonia and nitrogen compounds, causing eye irritation and the 'pool smell' while providing little sanitizing benefit.
What is the purpose of a pool Safety Vacuum Release System (SVRS)?
Answer: To prevent drain entrapment by releasing suction when a blockage is detected
An SVRS automatically shuts off or reverses pump suction when a drain blockage is detected, preventing dangerous suction entrapment injuries.
How should a pool maintenance technician document pool water chemistry readings?
Answer: In a pool log recording date, time, test results, and chemicals added
A complete pool log documenting all test results, chemical additions, and service actions is required by most state health codes and protects the property in case of incidents.
