One primary cause of escalating costs is conditioner. When administered in quantities over 19-30 ppm, it shields chlorine from sunlight so well that the chlorine is less effective.This causes the chemical controller to administer more chlorine to make up for the weak oxidation. If you add conditioner, keep the ppm at 10 or lower. You will experience a savings of up to 20% in chlorine consumption! Contact us for a water chemistry assessment today.
