Swimming Pool Pest Management | Hawai'i Approval #3538

Swimming Pool Pest Management


Course Description

One of the main factors in swimming pool maintenance is water chemistry. A few different facets need to be maintained. These include the organic content in the water, the pH of the water, total alkalinity, and calcium hardness. Additional factors are the temperature of the water, the concentration of disinfectant, and the amount of total dissolved solids. All of these factors are interconnected and each one influences the others.

After completing this course participants will be able to:

  • Identify the common pests of swimming pools.
  • Outline the facets of an integrated pest management approach to swimming pool management.
  • Discuss the intricacies of pool pH management.
