Mineraluxe - Alkalinity Plus

Raises total alkalinity to help prevent pH bounce and protect spa equipment. Keeps water balanced and comfortable for soaking.

Comes in a 750g 

What It Does

• Increases the alkaline mineral level (Total Alkalinity or TA) in your hot tub

• Ideal for use when TA is below 125 ppm, with a target range of 125–150 ppm

• Low TA may result in:

  • Unstable pH readings (commonly referred to as "pH bounce")

  • Metal corrosion and potential staining

  • Surface wear on plaster, grout, and acrylic

  • Increased likelihood of water problems and costly maintenance

• Made from premium-grade, food-safe minerals

• Micro-granular for rapid dissolution

• Alkaline in nature – measures approx. pH 8.3 in water

When to Use It

• Use as part of regular spa care to maintain Total Alkalinity between 125–150 ppm

• Essential after refilling your hot tub or monthly during routine water balancing

Dosage Guidelines

• 18 grams per 1,000 litres raises TA by 10 ppm

• 1 capful ≈ 10 grams

• Example: To increase TA by 20 ppm in a 1,000 L spa, use 36 grams

• Always test before and after treatment for accurate adjustments

How to Apply

• Adjust alkalinity before pH or calcium hardness

• Run the circulation pump with air valves closed

• Sprinkle product evenly over water surface

• Allow the water to circulate for 1–2 hours

• Retest TA and pH after treatment and adjust if necessary

Understanding Total Alkalinity (TA)

• Refers to the total concentration of buffering minerals in your water: primarily bicarbonates, carbonates, and hydroxides

• TA helps prevent sharp pH changes, acting as a stabilizer or “shock absorber”

• Proper TA levels help maintain overall water balance and improve water clarity

• Suggested range for hot tubs: 125–150 ppm

Why Balanced TA Matters

• Makes it easier to keep pH levels steady and within range

• Protects hot tub surfaces and components from corrosion and scale buildup

• Reduces chemical consumption and makes maintenance more predictable

• Promotes crystal-clear water and a more comfortable soaking experience

What Affects Total Alkalinity?

• TA drops over time due to acid use and chemical reactions

• Bromine tablets, pH reducers, and aeration can lower TA

• Tap or well water may affect TA based on local mineral content

• TA increases slightly when using pH increasers

Common TA Problems

When TA is too low:

• Causes wild pH swings (pH bounce)

• Corrodes metal surfaces

• Can lead to staining and water instability

When TA is too high:

• Makes it harder to lower pH

• Encourages calcium scale buildup

• Contributes to cloudy water
