These slow-dissolve calhypo tablets were specifically formulated for use in the poolife® NST® Tablet Feeder. They contain a stain and scale inhibitor and are packaged in modular pails for easy identification at shelf. Just like the NST® skimmer-fed tablets, these will destroy bacteria and organic contaminants without overstabilizing the pool or adding additional cyanuric acid.


  • NST® Feeder is for residential pools only up to 50,000 gallons
  • Follow poolife® NST® Feeder operating manual for specific tablet use
  • Do not mix these tablets with any other chlorine sanitizer product

These Tablets are designed for the NST feeder specifically (sold separately)
