Why:

• Raises pH of hot tub water
• Use when pH is less than 7.4 to return to effective range of 7.4 – 7.6
• Low pH causes;
  • Discomfort to bathers (acidic)
  • Rapid sanitizer dissipation
  • Corrosion of metal surfaces – staining
  • Premature aging of tub finishes
  • Etching of plaster, grout
  • Increased risk of problems and major repair costs
• Highest grade mineral available
  • Very fine, granular form
  • Alkaline – pH 11.6 in solution

When:

• Apply as needed to maintain pH between 7.4 – 7.6
• Test and adjust as often as necessary 

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 is based on how much the pH is to be raised:
  • If pH is 7.3 – use 6 grams per 1,000 L
  • If pH is 7.2 – use 12 grams per 1,000 L
  • < than 7.2 – use 24 grams per 1,000 L
• 1 capful = 10 grams (approx.)
• Never add more than 25 g per 1,000 L per application

How: 

• Operate pump with air off
• Apply product by sprinkling slowly over water surface
• Circulate for 1 – 2 hours
• Re-test to confirm proper pH or re-apply if pH is still below 7.4
