Pool Mate Pool Stabilizer Cyanuric Acid 28 lb – Fast-Dissolving Granular Conditioner, Extends Chlorine Life

Pool Mate 28-Pounds Premium Pool Stabilizer and Conditioner is a concentrated cyanuric acid formula designed to slow chlorine degradation from sunlight and extend your sanitizer’s effectiveness.

Keeping free chlorine active in outdoor pools is a constant battle against UV rays. This granular cyanuric acid product dissolves quickly to establish a protective buffer in pool water, helping your chlorine last longer and work more efficiently. Use a test kit to check cyanuric acid (CYA) levels and follow the dosing chart provided to reach the recommended range of 40–100 ppm.

How quickly will the stabilizer dissolve and start working?

The granules disperse fast when added to the skimmer or a warm-water pre-mix, and complete dissolution usually occurs after continuous recirculation for 24 hours. Proper filtration and circulation help the product spread evenly so it can protect the entire pool volume.

• Add slowly into the skimmer or premix in a pail of warm water.
• Run the pump continuously for 24 hours to fully dissolve.
• Ensure the filter is clean before application for best distribution.

What dose should I use to reach the recommended 40–100 ppm range?

If your pool is new, recently refilled, or currently has no stabilizer, add 4 ounces of this product per 1,000 gallons to begin building toward the 40–100 ppm target. Use the included chart or a CYA test to fine-tune additional additions until you reach the desired level.

• Initial addition for unstabilized pools: 4 oz per 1,000 gallons.
• Reference: 6 ounces of product raises CYA roughly 10 ppm per 5,000 gallons.
• Test CYA after 24 hours and adjust slowly to avoid overshooting the target.

How does this stabilizer affect chlorine use and pool chemistry?

Cyanuric acid acts as a sunlight shield for free chlorine, reducing photodegradation and often cutting chlorine consumption by as much as 25% under typical outdoor conditions. It does not replace chlorine but helps your sanitizer remain active longer; maintain free chlorine at 2.0–4.0 ppm and pH at 7.4–7.6 for balanced sanitation.

• Reduces chlorine loss due to UV exposure.
• Helps improve chlorine effectiveness when combined with correct chlorine residuals.
• Recommended CYA level: 40–100 ppm for outdoor pools.

How should I apply it safely and effectively?

Add the stabilizer slowly to the skimmer while the pump runs or dissolve it first in warm water and then pour it into the skimmer for easier distribution. Keep the pump running and the filter clean to promote full dissolution and uniform CYA levels throughout the pool.

• Add product slowly into the skimmer or premix in warm water.
• Run circulation continuously for at least 24 hours after application.
• Measure CYA with a reliable test kit and adjust gradually to maintain 40–100 ppm.

Who is this for: Pool Mate 28-Pounds Premium Pool Stabilizer and Conditioner is aimed at owners of outdoor inground and aboveground pools who want to reduce chlorine loss from sunlight, extend their sanitizer’s life, and lower routine chlorine consumption. It’s suitable for anyone comfortable testing and adjusting cyanuric acid levels, maintaining a 2.0–4.0 ppm chlorine residual, and keeping pH between 7.4 and 7.6. Ideal for seasonal prep, new fills, or stabilizer maintenance when CYA testing shows levels below the recommended range.
