Florida Drinking Water Operator "B" Practice Test

What type of chlorine formulation is typically used for swimming pool sanitation?

1. Calcium hypochlorite

2. Sodium hypochlorite

3. Liquid chlorine

4. Chlorine tablets

The correct answer is: Chlorine tablets

Chlorine tablets are commonly used for swimming pool sanitation because they are highly effective, easy to use, and provide a controlled release of chlorine over time. This slow dissolution helps maintain a consistent level of chlorine in the pool water, ensuring effective disinfection and helping to prevent the growth of harmful bacteria and algae. Tablets are generally stable and can be conveniently added to the skimmer or a floating dispenser, which makes them a practical choice for regular maintenance. Calcium hypochlorite and sodium hypochlorite are indeed other forms of chlorine used in various applications, including pool sanitation, but they are typically more reactive or require more frequent handling than tablets. Liquid chlorine, while effective, can also pose handling risks and may require more precise dosing compared to the straightforward application of tablets.
