Why is it important to maintain proper levels of free chlorine in pool water?

to balance water temperature
to destroy harmful organisms
to reduce water evaporation
to stabilize pH

The correct answer is: to balance water temperature

Maintaining proper levels of free chlorine in pool water is important because it helps to destroy harmful organisms present in the water. Free chlorine acts as a disinfectant, effectively killing bacteria, viruses, and algae that can contaminate the pool and cause illnesses in swimmers. By ensuring the correct amount of free chlorine is present in the water, pool operators can provide a safe and sanitary swimming environment for patrons.
