Pool Mate Cyanuric Acid Pool Stabilizer 4 lb — Granulated Conditioner, Fast-Dissolving for Outdoor Pools

Pool Mate 4-Pounds Premium Pool Stabilizer and Conditioner is a cyanuric acid treatment that helps protect and extend the life of free chlorine in outdoor pools.

Keep outdoor pools more resistant to sun-driven chlorine loss by using Pool Mate cyanuric acid. This granulated stabilizer dissolves quickly when added via the skimmer or pre-dissolved in warm water, raising the cyanuric acid (CYA) level to the recommended 40–100 ppm range. Proper use reduces the frequency of shocking and lowers the amount of chlorine needed to maintain a steady residual when combined with regular testing and filtration.

How fast will Pool Mate dissolve and start protecting my chlorine?

The formula disperses rapidly when added to circulating water, and full dissolution is achieved within 24 hours of continuous recirculation. For faster distribution, premix the granules in a warm pail of water before pouring into the skimmer.

• Fully dissolves with 24 hours of circulation
• Add slowly to skimmer to avoid clouding
• Premixing in warm water speeds the process
• Ensure filter is clean prior to adding

How much Pool Mate do I need to reach the right cyanuric acid level?

Use the included chart or a pool test kit to determine current CYA and target level (40–100 ppm). As a general guide, 6 ounces of this product raises CYA about 10 ppm in 5,000 gallons; for new or refill situations add 4 oz per 1,000 gallons to approach the 40–100 ppm range.

• 6 oz per 5,000 gallons ≈ +10 ppm CYA
• 4 oz per 1,000 gallons recommended for new/refilled pools
• Measure CYA after 24 hours to confirm level
• Adjust incrementally — CYA accumulates over time

What application steps and water chemistry should I follow for best results?

Add the stabilizer slowly into the skimmer with the circulation pump running, or premix and pour into the skimmer. After adding, run filtration continuously for 24 hours and retest cyanuric acid, free chlorine, and pH. Maintain free chlorine at 2.0–4.0 ppm and pH between 7.4–7.6 for balanced performance.

• Run pump continuously 24 hours after addition
• Keep free chlorine 2.0–4.0 ppm
• Maintain pH 7.4–7.6 for best sanitizer efficiency
• Retest using a reliable kit before further dosing

Will adding cyanuric acid change my maintenance routine?

Adding Pool Mate reduces sunlight-driven chlorine degradation, so you may experience steadier chlorine levels and fewer emergency additions. However, CYA accumulates and should be measured periodically; excessive CYA can require partial dilution by water replacement rather than continued additive dosing.

• Leads to more stable chlorine readings under sunlight
• Does not replace regular testing and filtration
• High CYA requires dilution rather than more product
• Follow label directions and the included dosing chart

Who this is for: Pool Mate 4-Pounds Premium Pool Stabilizer and Conditioner is aimed at owners of outdoor swimming pools who want to protect their chlorine from UV loss and reduce the frequency of shock treatments. It suits new or refilled pools, seasonal top-ups, and routine maintenance for vinyl, concrete, or fiberglass pools when used with proper testing and balanced water chemistry.
