Product details:

Ensure Conditioner is a once-a-season treatment that provides the foundation for the Ensure System, imparting sparkling clear water and improved swimmer comfort. This product is not lost through evaporation, is not affected by sunlight, and does not affect other chemicals. It is lost only through backwash-to-waste and swimmer 'splash-out.' In addition to imparting sparkling clear water and improved swimmer comfort, Ensure Conditioner does not affect pH when added to the pool.
