Poolife™ NST™ Prime Cal Hypo Tablets, 20.2 lb - Free Shipping
Poolife™ NST™ Prime Cal Hypo Tablets are slow-dissolving pool chlorine tablets designed to sanitize swimming pool water without adding cyanuric acid, also known as CYA. This makes them a strong choice for pool owners who want reliable chlorine performance while helping avoid the over-stabilization problems that can occur when CYA levels get too high.
The 20.2 lb size is a convenient larger container for routine pool maintenance through the swim season. These extended-release Cal Hypo tablets help maintain clean, clear, swim-ready water and are designed for use in compatible skimmers, Poolife™ NST™ Feeders, or Poolife™ NST™ Floaters.
Slow-Dissolving Chlorine Tablets Without Added CYA
Poolife™ NST™ Prime is designed for pool owners who want effective chlorine sanitizing without adding more stabilizer to the water. Unlike traditional stabilized chlorine tablets, these Cal Hypo tablets do not contribute additional CYA, which helps pool owners maintain better control over water balance.
This is especially helpful for pools that already have elevated cyanuric acid levels or for homeowners who want to manage stabilizer separately. By helping reduce the risk of chlorine lock, Poolife™ NST™ Prime supports more consistent chlorine effectiveness when used as directed.
Extended-Release Cal Hypo for Consistent Pool Sanitizing
These slow-dissolving tablets are made to release chlorine over time, providing lasting sanitizer coverage for everyday pool care. The extended-release format helps reduce frequent handling while supporting steady chlorine maintenance between water tests.
Poolife™ NST™ Prime is a practical sanitizer for weekly pool maintenance, especially when paired with proper filtration, water circulation, routine testing, and balanced pool chemistry.
Larger 20.2 lb Size for Seasonal Pool Maintenance
The 20.2 lb container offers a larger supply than smaller household sizes, making it a good fit for pool owners who want to stock up for regular use. It is especially useful during peak swim season when chlorine demand can increase due to sunlight, heat, rain, and heavier swimmer use.
This size is ideal for homeowners who already use the Poolife™ NST™ system or who prefer a CYA-free Cal Hypo tablet option for ongoing chlorine maintenance.
Designed for Compatible Skimmers, NST Feeders, and NST Floaters
Poolife™ NST™ Prime Tablets should be used only with compatible equipment. These tablets are designed for use in a clean skimmer basket, Poolife™ NST™ Feeder, Poolife™ NST™ Floater, or a delivery system specifically designed for Cal Hypo tablets.
Do not place these tablets in a feeder or floater that has been used with trichlor, dichlor, bromine, or other incompatible pool chemicals unless the equipment is specifically approved and properly cleaned according to manufacturer instructions.
Product Details
How to Use
-
Test pool water first: Check free chlorine, pH, total alkalinity, calcium hardness, and CYA before adding tablets.

Use compatible equipment only: Place tablets in a clean skimmer basket, Poolife™ NST™ Feeder, Poolife™ NST™ Floater, or Cal Hypo-compatible delivery system.
-
Adjust based on demand: Add tablets as needed to maintain proper chlorine levels based on pool size, swimmer load, heat, rainfall, and sunlight exposure.
-
Maintain free chlorine: Keep free chlorine within the recommended 1 to 4 ppm range.
-
Monitor water balance: Since Cal Hypo can affect calcium hardness, test regularly and adjust pool chemistry as needed.
