Chlorine Stabiliser Cyanuric Acid 4kg

• 4 kg bucket of chlorine stabiliser for outdoor swimming pools
• Raises cyanuric acid CYA levels in pool water
• Helps protect free chlorine from rapid breakdown by UV sunlight
• Particularly useful with unstabilised chlorine such as calcium hypochlorite or liquid chlorine
• Helps maintain a more consistent chlorine residual during hot, sunny weather
• Useful after a fresh fill, large water replacement or when testing shows stabiliser is too low
• Especially relevant for outdoor pools exposed to strong Mediterranean sunshine
• Granular format allows the required quantity to be measured according to pool volume and test results

✓ Helps chlorine remain effective for longer instead of being rapidly lost to sunlight
✓ Correct stabiliser levels can reduce chlorine waste and make routine pool care more consistent

Technical Information

• Brand: RIVAL
• Product type: Chlorine stabiliser
• Chemical type: Cyanuric acid CYA
• Pack size: 4 kg
• Format: Granules
• Application: Raising and maintaining cyanuric acid levels in outdoor swimming pools
• Dosage: 1 kg raises cyanuric acid by approximately 20 ppm in 50 m³ of pool water

• Test the cyanuric acid level before adding stabiliser and dose according to the instructions on the product label
• Particularly useful when using unstabilised chlorine products or saltwater chlorination systems
• Cyanuric acid does not disappear quickly through normal chlorination, so avoid adding more without testing first
• Excessive stabiliser can reduce chlorine effectiveness, so regular CYA testing is important
• After significant water replacement, backwashing or heavy rainfall, retest before deciding whether additional stabiliser is required
• Example: for a 50 m³ pool, add 1 kg to increase stabiliser by approximately 20 ppm
• Store securely in the original container in a cool, dry place away from moisture and other pool chemicals
