Why:

• Raises Calcium Hardness (CH) 
• Use when calcium hardness is less than 100 ppm to return to effective range of 100 – 200 ppm
• Low CH causes;
  • Etching of plaster, grout
  • Increased overall corrosion of surfaces – staining
  • Increased risk of problems and major repair costs
• Highest grade mineral available
  • Clean, granular, ‘prill’ form
  • Dissolves quickly and fully – even in hot water
  • Lowest impurity level available

When:

• Apply when needed to maintain CH between 100 – 200 ppm
• Always test with fresh fill and monthly thereafter

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:

• To raise calcium hardness: 
  • 10 g per 1,000 L raises calcium hardness by 10 ppm
• 1 capful = 10 grams (approx.)

How:

• Always adjust calcium hardness after total alkalinity and pH
• Operate pump with air off
• Divide total amount of Mineraluxe Calcium Plus into 3 equal applications
• Apply 1 application every 3 hours by sprinkling slowly over water surface – do not attempt to predissolve
• Circulate for 1 – 2 hours
