Robelle 28-Pounds Premium Pool Stabilizer & Cyanuric Acid — Extend Chlorine Life

Premium protection for your pool chemistry

When you swim in sunlit water, you want chemistry that lasts. Robelle 28-Pounds Premium Chlorine Stabilizer and Conditioner delivers concentrated cyanuric acid to shield chlorine from UV rays, helping it stay effective longer and supporting a more stable pool experience. The result can feel like clearer water, steadier readings, and fewer dosing surprises on hot days.

Designed for a range of swimming pools, this stabilizer helps bring cyanuric acid levels into the recommended 40–100 ppm window. Proper stabilization may improve chlorine efficiency and can help reduce overall chlorine use, depending on your climate and sun exposure. The stabilizer works by forming a protective shield around chlorine molecules, which can translate to steadier disinfection performance and a more inviting swim surface.

Key Benefits at a Glance

• Pool-ready cyanuric acid to shield chlorine from sunlight
• Helps reduce chlorine loss due to UV exposure
• Recommended cyanuric acid level: 40–100 ppm
• 6 ounces raise cyanuric acid by about 10 ppm per 5,000 gallons
• Increases cyanuric acid levels to support chlorine stability
• Potentially reduces chlorine consumption by up to 25%
• Improves chlorine effectiveness for clearer water

Usage Guidelines for Best Results

Follow the included chart to bring pool water into the 40–100 ppm range. For new, freshly refilled, or unstabilized pools, add 4 oz per 1,000 gallons to reach the target range. Dissolve slowly by pouring into the skimmer, or premix in a bucket of warm water and then add to the skimmer. Ensure the filter is clean and recirculate for 24 hours to dissolve completely. Maintain a chlorine residual of 2.0–4.0 ppm and a pH of 7.4–7.6 for balanced water.

• 4 oz per 1,000 gallons as a starting dose for new or refreshed pools
• Keep stabilizer levels in the 40–100 ppm range
• Chlorine residuals: 2.0–4.0 ppm; pH: 7.4–7.6
• Test water regularly with a reliable test kit

Real-Life Scenarios and Practical Tips

Pool owners often notice more consistent chlorine performance after sunny days, less fluctuation in readings, and smoother routine dosing. A stabilized pool can feel more comfortable to swim in and may offer a easier maintenance rhythm, especially during peak season or in climates with strong UV exposure. This product is intended to support chlorine longevity as part of a comprehensive water-care routine.

Note: This information reflects product capabilities to support chlorine stability. Always follow local guidelines, use a good test kit, and adjust dosing based on pool size, usage, and climate conditions.
