• Raises pH quickly and efficiently
• Raises alkalinity levels without causing "pH bounce"
• Ensures bather comfort by stabilizing pH
• Elongates the life of equipment when pH is in proper balanc

Why

• Raises pH of hot tub water
• Use when pH is less than 4 to return to effective range of 7.4 – 7.6
• Low pH causes;
  • Discomfort to bathers
  • Rapid sanitizer dissipation
  • Corrosion of metal surfaces - staining
  • 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 – 6

How Much

• Dosage rate is based on how much the pH is to be raised:
  • If pH is 3 – use 6 grams per 1,000 L
  • If pH is 2 – use 12 grams per 1,000 L
  • < than 2 – use 24 grams per 1,000 L
• 1 capful = 10 grams (approx.)
• Never add more than 25 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 4
