Quick Steps


  • Dazzle Instant UV Block stabilizes pool water to prevent chlorine loss from the ultraviolet rays of the sun
  • Without stabilizer being present, it would be very difficult to maintain a chlorine residual on a bright sunny day without increasing the amount of chlorine used significantly (more than 6 times as much)
  • Stabilizer is also proven to slow the rate of degradation of vinyl liners, allowing them an increased life span in pools 
  • The ideal level for stabilizer in a chlorinated, outdoor swimming pool is 30 – 40 ppm
  • Once a stabilizer level reaches approx. 30 ppm, no more benefit can be achieved by adding more stabilizer
  • There is plenty of confusion surrounding elevated stabilizer levels
    • Once levels reach 100 ppm, it is recommended that the water be diluted with fresh water to lower to <100 ppm
    • There is no effective way to lower stabilizer levels other than to drain water and refill with water that has no stabilizer present (dilution)  


  • Dazzle Instant UV Block should be used to raise the stabilizer level any time it is less than 20 ppm
  • When stabilized chlorines are used regularly, the stabilizer level is unlikely to ever require topping up
  • When unstabilized chlorines are used, or the pool is a salt pool, periodic top-ups are likely to be required based on the amount of water lost to backwashing, draining and splash-out

How Much:

  • 330 mls per 10,000 litres will raise stabilizer by 10 ppm
  • In a freshly-filled swimming pool, add 1 litre per 10,000 litres to achieve the ideal starting level of approx. 30 ppm 


  • The best application method for Dazzle Instant UV Block is as follows;
    • Shake well and simply pour the required amount around the edges of the pool
    • If any of the product is visible in the pool, use the pool brush to mix it into the water 
    • When the bottle is empty, triple rinse to ensure all the contents have been added
    • Simple and easy – with instant results
  • Alternatively, the required amount of product can be poured slowly into the skimmer
    • Backwash or clean the filter prior to applying in this way
    • Do not backwash for 24 hours to ensure all the product has left the filter
