Description
Overview
Poolife NST Prime Tablets provide a powerful and convenient way to sanitize pool water without the risk of over-stabilization. These slow-dissolving calcium hypochlorite tablets are designed for use with the Poolife NST Feeder or in a skimmer basket. The formula effectively destroys bacteria and organic contaminants while maintaining proper chlorine levels without adding cyanuric acid.
NST Prime tablets are compatible with chlorine pools, salt chlorine generators, ozone systems, and mineral sanitation systems. Their slow-dissolving design provides consistent sanitation while helping maintain balanced water chemistry throughout the swimming season.
