Poolife™ NST™ Prime Cal Hypo Tablets, 9 lb
Poolife™ NST™ Prime Cal Hypo Tablets are slow-dissolving chlorine tablets designed to sanitize swimming pool water without adding cyanuric acid, also known as CYA. This makes them a smart option for pool owners who want long-lasting chlorine performance while helping avoid the over-stabilization issues commonly associated with traditional trichlor tablets.
The 9 lb container is ideal for routine residential pool maintenance, providing a convenient supply of extended-release Cal Hypo tablets for use in compatible skimmers, Poolife™ NST™ feeders, or Poolife™ NST™ floaters. Each tablet helps destroy bacteria, support clear water, and maintain a proper chlorine residual when used as directed.
Slow-Dissolving Cal Hypo Chlorine Without Added CYA
Poolife™ NST™ Prime Tablets use Cal Hypo technology to deliver effective pool sanitization without adding stabilizer to the water. Because these tablets do not add CYA, they are especially useful for pools where cyanuric acid levels are already high or where the pool owner wants more control over water balance.
This non-stabilized chlorine approach helps reduce the risk of chlorine lock, which can happen when CYA builds up and reduces chlorine effectiveness. For outdoor pools, always test and balance water regularly, including stabilizer levels, to maintain proper protection from sunlight and consistent sanitizer performance.
Extended-Release Tablets for Easier Pool Care
These slow-dissolving pool chlorine tablets are built for lasting sanitization. Rather than dissolving all at once, Poolife™ NST™ Prime Tablets are designed to release chlorine over time, helping maintain clean, swim-ready water with less frequent handling.
They are a strong choice for weekly pool care, routine sanitizing, and ongoing chlorine maintenance during the swimming season. Use them as part of a balanced pool-care routine that includes regular testing, proper circulation, and shock treatment when needed.
Helps Keep Pool Water Clear, Clean, and Swim-Ready
Poolife™ NST™ Prime Cal Hypo Tablets help destroy bacteria and organic contaminants while supporting clearer pool water. The formula is designed for effective sanitization without contributing to CYA buildup, making it a helpful solution for pool owners looking to maintain chlorine performance over time.
Because Cal Hypo products can affect calcium hardness, pool water should be tested regularly and balanced according to the product label and local water conditions.
Product Details
How to Use
-
Test the pool water first: Check free chlorine, pH, alkalinity, calcium hardness, and CYA before adding tablets.
-
Use compatible equipment: Place tablets only in a compatible skimmer, Poolife™ NST™ Feeder, Poolife™ NST™ Floater, or Cal Hypo-compatible delivery system.
-
Maintain proper chlorine: Adjust tablet quantity as needed to maintain 1 to 4 ppm free chlorine.
-
Monitor pool conditions: Hot weather, heavy swimmer use, rainfall, and sunlight can increase chlorine demand.
-
Never mix chemicals: Do not mix Cal Hypo tablets with trichlor, dichlor, bromine, shock, or any other pool chemical in the same feeder, floater, skimmer, or storage container.
Important Compatibility and Safety Notes
Poolife™ NST™ Prime Tablets are Cal Hypo tablets and should not be used in feeders or floaters designed only for trichlor tablets. Mixing Cal Hypo with trichlor, dichlor, or other chemical residues can create a dangerous reaction.
Use only clean, compatible equipment designed for Cal Hypo tablets. If switching from another chlorine type, follow the manufacturer’s instructions and make sure the feeder, floater, or skimmer is free of chemical residue before use.
Store tablets in the original container in a cool, dry, well-ventilated area. Keep the container closed when not in use, and always follow the product label for handling, dosing, storage, and reentry instructions.
Why Choose Poolife™ NST™ Prime 9 lb?
The 9 lb size is a practical option for pool owners who want an easy-to-manage container of slow-dissolving Cal Hypo tablets. It offers enough product for ongoing pool care without the bulk of larger professional-size containers.
Poolife™ NST™ Prime is especially helpful for pools where CYA management matters. Since the tablets sanitize without adding cyanuric acid, they help maintain chlorine effectiveness while giving pool owners more control over stabilizer levels.
