Swimables Cyanuric Acid Pool Stabilizer 8 lb — Fast-Dissolving Granules, Max Strength UV Protection

Swimables 8-Pounds Max Strength Cyanuric Acid is a fast-dissolving pool stabilizer that preserves chlorine so your pool or hot tub stays clearer longer.

Maintaining effective chlorine levels can feel like a constant battle when sunlight constantly breaks down sanitizer. This Swimables pool stabilizer (cyanuric acid) is formulated to slow UV degradation of chlorine for inground pools, spas and saltwater systems. The quick-dissolving granules let you add protection without long wait times, and the 8-pound size gives several treatments depending on pool volume and target stabilization level.

How does this stabilizer protect my pool’s chlorine?

Swimables cyanuric acid forms a lightweight shield around free chlorine, reducing how quickly ultraviolet light neutralizes the sanitizer. That means your chlorine lasts longer between additions, helping keep sanitizer levels steady during sunny days.

• Contains concentrated cyanuric acid designed to bond with free chlorine.
• Reduces ultraviolet breakdown of chlorine in outdoor pools.
• Works with stabilized chlorine products and saltwater chlorine generators.
• Helps extend time between chlorine boosts for routine maintenance.

How do I add Swimables pool conditioner to my pool or spa?

For best results, dissolve measured amounts in a clean bucket of water before distributing it around the pool’s deep end with the pump running. Add small increments to avoid overshooting target cyanuric acid levels, and retest after circulation to confirm concentration.

• Measure by pool volume and target ppm — follow label guidance.
• Dissolve a small scoop in water, then pour slowly with pump on.
• Wait at least 8–24 hours, then retest cyanuric acid and free chlorine.
• Adjust future doses based on test results and exposure to sunlight.

Will this work with saltwater pools and hot tubs?

Yes — the formulation is suitable for salt chlorination systems and conventional pools, but hot tubs require careful dosing because smaller volumes reach higher concentrations quickly. Use smaller increments for spas and retest often to avoid excessive stabilization levels.

• Compatible with saltwater chlorine generators and traditional chlorination.
• Use much smaller amounts in hot tubs to prevent overly high cyanuric acid.
• Ideal for inground pools exposed to strong sunlight.
• Monitor levels with a cyanuric acid test kit after each addition.

How quickly does it dissolve and how often should I add it?

Swimables is formulated to dissolve faster than many granular stabilizers, so you’ll see results in circulation sooner. Frequency depends on pool size, sunlight exposure and initial cyanuric acid target; many pool owners add it at season start and top up as needed.

• Quick-dissolving granules reduce wait time before testing and resuming normal treatments.
• Typical use is an initial dose at season opening, with occasional maintenance additions.
• Frequent testing guides top-ups rather than calendar-based dosing.
• Avoid adding more if cyanuric acid already meets recommended levels.
