pH Minus

$25.47$54.12

pH Minus lowers pH and Total Alkalinity. A fast-dissolving, highest quality granular formulation, it safely lowers levels when compared to more toxic and dangerous liquid acids.  Quality matters with balancing products so they don’t introduce unwanted impurities. A balanced pH prevents corrosion and scale-formation, allows sanitizers to work more efficiently, prevents cloudy water and is largely responsible for the overall comfort of the water.

Quick Steps

Why:

  • Safely lowers pH and total alkalinity in pool water when needed
  • A high pH can cause the following issues:
    • Discomfort to bathers
    • Poor sanitizer efficiency, especially with chlorine
      • Chlorine becomes weak and ineffective as pH elevates
    • An increased risk of scale formation, especially inside pool heaters and salt chlorinator cells
    • Cloudy water

When:

  • See your Dazzle™ Retailer for a personalized water analysis. When the pH and/or total alkalinity of your pool water is high, use Dazzle pH Minus to lower it. 
  • Test pH as often as needed to maintain consistently at the following ranges;
    • Ideal: 7.4 – 7.6
    • Acceptable: 7.2 – 7.8 
  • Use Dazzle pH Minus whenever the pH is greater than 7.6 to bring back to the ideal and effective range of 7.4 – 7.6
  • The recommended total alkalinity level is based on your pools surface type:
    • Plaster, marblesheen, fully-tiled: 80 – 125 ppm
    • Vinyl, paint, fiberglass, acrylic: 125 – 150 ppm
  • Apply Dazzle pH Minus whenever the total alkalinity is high and needs lowering.

How Much:

  • To lower pH:
    • If pH is 7.7:  use 60 grams per 10,000 litres
    • If pH is 7.8 – 7.9:  use 120 grams per 10,000 litres
    • If pH > 8.0:  use 180 grams per 10,000 litres (multiple applications may be needed)
  • To lower total alkalinity:
    • 240 grams per 10,000 litres lowers total alkalinity by 10 ppm
    • It is always best to lower total alkalinity slowly so as not to dramatically lower the pH at the same time
    • Divide the total amount of Dazzle pH Minus needed to lower the Total Alkalinity by the maximum daily amount to establish the number of days to apply the product over
    • Add that quantity each day to safely and slowly lower the total alkalinity
    • Daily Maximum: Never add more than 240 grams per 10,000 litres per day

How: 

  • Pump and filter should be operating 
  • Sprinkle or broadcast evenly across water surface when pool is not being used 
  • Circulate water for 1 – 2 hours 
    • For pH: re-test to confirm or re-apply if pH is still above 7.6
    • For total alkalinity: When lowering TA, lower slowly (10 ppm per day). Never allow pH to drop below 7.2
