Conditioner is the layman’s term for cyanuric acid. Cyanuric acid provides a molecular bond to chlorine to extend the life of chlorine in the pool. Without it, maintaining a chlorine residual between service calls would be impossible, resulting in cloudy, algae conditions. Our company checks conditioner levels throughout the year, and adds when necessary. This service is billed annually in the month of March at $60.00 per year.
