text: When a swimmer enters a pool, they add up to one billion organisms to the water. Chlorination kills all organisms harmful to swimmers such as those that cause ear infections and athlete's foot. The advantages of electrochlorination in this process are as follows:
  *Not irritating to skin or soft tissue.
  *Active in small concentrations.
  *Longer lifespan of chemical and therefore less replacement necessary.
  *Easily measurable.
