PoolFix Stabilizer & Conditioner – 100% Granular Cyanuric Acid (CYA) for Pool Chlorine Protection

PoolFix Stabilizer & Conditioner is 100% pure granular cyanuric acid — the industry-standard chemical used to shield pool chlorine from UV degradation and extend its active life in outdoor pools. Without a proper CYA level, sunlight can destroy up to 75–90% of free chlorine within just two hours, dramatically increasing chemical consumption and leaving your pool vulnerable to bacteria and algae. PoolFix CYA bonds with chlorine molecules to buffer them against photodecomposition, allowing your sanitizer to work more efficiently and consistently throughout the season. Available in both pouches and buckets to suit any application — from single-pool residential service to high-volume commercial routes.

• ✔ 100% pure cyanuric acid — no fillers or additives; raises CYA levels precisely and predictably for accurate water chemistry management
• ✔ Protects chlorine from UV degradation — prevents sunlight from wiping out free chlorine, reducing chlorine consumption by up to 25% and extending sanitizer longevity
• ✔ Granular formula for easy dosing — dissolve in a bucket of water and add through the skimmer, or broadcast directly; compatible with all standard application methods
• ✔ Ideal for liquid chlorine and salt systems — essential for pools using unstabilized chlorine sources (liquid chlorine, Cal-Hypo, salt chlorine generators) that add no CYA on their own
• ✔ Compatible with all pool surface types — safe for plaster, vinyl liner, fiberglass, aggregate, and painted surfaces; above-ground and in-ground
• ✔ Available in pouches and buckets — flexible packaging options for residential pool owners and professional service companies alike

Target CYA range: 30–50 ppm for standard chlorinated pools; 60–80 ppm for saltwater chlorine generator systems. Dosage: approximately 1 lb per 4,000 gallons raises CYA by 30 ppm. Add through the skimmer with the pump running; allow 24–48 hours to fully circulate before retesting. Maintain pH between 7.2–7.6 for optimal chlorine efficiency. Do not backwash for at least one week after adding to allow full dissolution.
