Mineraluxe pH Minus 950g


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.

Lowers pH and Total Alkalinity
Size: 950 GM
Product Code: DML09546

Quick Steps


  • Safely lowers pH and Total Alkalinity (TA)
  • Use when pH is more than 7.6 to return to effective range of 7.4 – 7.6
  • Use when TA is greater than 150 ppm
  • High pH causes;
    • Discomfort to bathers
    • Poor sanitizer efficiency
    • Scale formation
    • Cloudy water
    • Increased risk of problems and major repair costs
  • Highest grade mineral available
    • Fine, granular form


  • Apply as needed to maintain pH between 7.4 – 7.6
  • Apply when required to lower TA

As a general rule, a Mineraluxe tub requires less testing and re-balancing due to:

  • The stabilizing effects of the Mineraluxe system
  • The dramatic decrease in products and product quantities applied

How Much:

  • Dosage rate to lower pH is based on:
    • How much the pH is to be lowered,
    • A balanced total alkalinity. If TA is out of balance, adjust it first:
      • pH 7.7 to 7.9 – use 8 g per 1,000 L
      • pH 8.0 to 8.4 – use 12 g per 1,000 L
      • > than 8.4 – use 15 g per 1,000 L
  • To lower TA:
    • 24 g per 1,000 L lowers TA 10 ppm
  • 1 capful = 10 grams (approx.)
  • Never add more than 24 g per 1,000 L per application


  • Operate pump with air off
  • Apply product by sprinkling slowly over water surface
  • Circulate for 1 – 2 hours
  • For pH: Re-test to confirm – re-apply if pH is still above 7.6
  • For TA: When lowering TA, never allow pH to drop below 7.2
    • Lower TA slowly – by 10 ppm per day
