pH Plus Super – Sodium Bicarbonate Alkalinity Increaser

Product Overview

pH Plus Super is a granular alkalinity increaser containing Sodium Bicarbonate (NaHCO₃), commonly known as baking soda or bicarb. It is used to raise total alkalinity in pool water to the recommended range of 80–120 mg/L, providing pH buffering stability and reducing pH drift.

Sodium Bicarbonate acts as a buffering agent in pool water through the carbonate-bicarbonate equilibrium system. Adequate total alkalinity prevents rapid pH fluctuations (“pH bounce”), which is critical for chlorine efficacy and swimmer comfort.

pH Plus Super is distinct from pH Plus (Sodium Carbonate/Soda Ash). While both products raise pH, pH Plus Super’s primary pool use is total alkalinity adjustment, providing the stable chemical buffer that prevents pH drift. pH Plus has a stronger and more direct pH-raising effect. As noted in the reference guide, pH Plus Super is described as a product that “raises alkalinity to provide pH stability and clearing cloudy pools faster.”

How It Works

pH Plus Super works through the carbonate-bicarbonate buffer system, which stabilises pH in pool water.

The alkalinity increase process involves:

• Dissolution – Sodium Bicarbonate granules dissolve in water, releasing sodium (Na⁺) and bicarbonate (HCO₃⁻) ions
• Buffer formation – Bicarbonate ions react with hydrogen ions (H⁺) to form carbonic acid (H₂CO₃), which then dissociates to form water and carbon dioxide
• pH stability – The carbonate-bicarbonate buffer system resists pH changes when acids or bases are added
• Mild pH effect – Bicarbonate has a mild pH-raising effect, much gentler than sodium carbonate
• Alkalinity reservoir – Total alkalinity provides a reservoir of buffering capacity

The bicarbonate buffer system is the primary mechanism by which pool water resists pH change. Without adequate alkalinity, pH can swing dramatically with the addition of acids or bases.

Why It Matters

• pH stability is the primary reason pH Plus Super matters. Without adequate total alkalinity, pool water experiences “pH bounce” – rapid, unpredictable pH fluctuations that make water chemistry difficult to manage.
• Chlorine efficacy depends on stable pH. When pH fluctuates, chlorine effectiveness varies. At pH above 7.6, chlorine becomes less effective. At pH below 7.2, chlorine becomes too aggressive. Stable pH ensures optimal chlorine performance.
• Swimmer comfort is improved when pH is stable. pH fluctuations can cause eye and skin irritation, even if pH occasionally falls within the acceptable range.
• Equipment protection is enhanced by stable pH. pH swings can accelerate corrosion or scale formation, damaging pool equipment and surfaces.
• Water clarity is improved when alkalinity is balanced. Low alkalinity can cause cloudy water, as noted in the reference guide. Correcting alkalinity helps clear cloudy pools faster.

Key Benefits

1. Safe, Gentle Alkalinity Adjustment
   pH Plus Super provides a safe and gentle way to raise total alkalinity without dramatically overshooting pH, unlike soda ash (sodium carbonate).
2. Prevents pH Bounce
   Adequate total alkalinity (80–120 mg/L) prevents rapid pH fluctuations, making water chemistry easier to manage.
3. Improves Chlorine Efficiency
   Stable pH ensures chlorine remains effective at the optimal level, maximising sanitisation while minimising chlorine consumption.
4. Inexpensive and Widely Available
   Sodium Bicarbonate is a common, affordable chemical available from multiple suppliers, including food-grade and technical-grade sources.
5. No Significant Handling Hazards
   Sodium Bicarbonate has low toxicity and is generally recognised as safe (GRAS) by food safety standards at low concentrations.
6. Will Not Dramatically Overshoot pH
   Unlike sodium carbonate, sodium bicarbonate has a mild pH effect, making it difficult to accidentally overshoot pH targets.
7. Helps Clear Cloudy Pools
   As noted in the reference guide, pH Plus Super helps clear cloudy pools faster by stabilising pH and supporting proper water balance.

Dosage & Application Guidance

Dosage requirements vary depending on manufacturer specifications, pool volume, contaminant load, water chemistry, bather load, environmental conditions, and treatment objectives. Always follow product label instructions and professional water test results.

Based on the reference guide, typical guidance includes:

• General guidance: 1.5 kg per 10,000 litres to raise total alkalinity by approximately 10 mg/L (ppm)
• Method: Broadcast dissolved product around pool with pump running
• Target total alkalinity: 80–120 mg/L
• Retest: After 6–8 hours

Important: Always correct total alkalinity before adjusting pH for the most effective results. pH Plus Super has a mild pH effect – for significant pH adjustment, use pH Plus (Soda Ash/Na₂CO₃).

Step-by-Step Application Guide

Before Treatment:

1. Test pool water for total alkalinity and pH
2. Confirm total alkalinity is below 80 mg/L before adding pH Plus Super
3. Calculate required dosage based on pool volume and current TA
4. Do not adjust pH until alkalinity is corrected
5. Gather required PPE: gloves, safety goggles

During Treatment:

1. Fill a clean bucket with pool water (not fresh water)
2. Add the measured pH Plus Super granules to the bucket water
3. Stir until fully dissolved (dissolves readily)
4. With the pool pump running, broadcast the solution evenly around the pool perimeter
5. Allow the pump to run for at least 6–8 hours for proper circulation

After Treatment:

1. Retest total alkalinity after 6–8 hours
2. If TA is still below 80 mg/L, repeat the dosing process
3. Once TA is within 80–120 mg/L, adjust pH using pH Plus or pH Minus as needed
4. Retest pH and adjust accordingly

Troubleshooting:

• Alkalinity not increasing sufficiently: Check pool volume calculation; ensure product is fully dissolved and circulated
• Alkalinity overshot target: Alkalinity cannot be easily lowered; partial drain and refill may be required
• pH still fluctuating: Ensure alkalinity is stable before adjusting pH
