Keep your pool water balanced, comfortable, and equipment-safe with pH Up Pool pH Increaser, available in 750g, 2kg, and 20kg sizes. Formulated with fast-dissolving sodium carbonate (soda ash), this powerful pH increaser quickly raises low pH levels and helps maintain the ideal swimming range of 7.2 – 7.8.

Maintaining proper pH is essential for swimmer comfort, chlorine efficiency, and long-term protection of pool surfaces and equipment. When pH drops below 7.2, water becomes acidic — leading to corrosion, irritation, and rapid sanitizer loss.

Why Maintaining Proper pH Matters

✔ Prevents burning eyes and dry, itchy skin
✔ Protects metal ladders, pipes, and heaters from corrosion
✔ Reduces plaster and concrete etching
✔ Improves chlorine efficiency and stability
✔ Prevents costly equipment damage

High pH (above 7.8) can cause scaling and reduce chlorine effectiveness, while low pH (below 7.2) increases corrosion and irritation. Always adjust pH before adding chlorine for best results.

• 20kg – Best for large 30' -33' above grounds and 18x36 or larger inground pools or commercial applications

When to Use pH Up

Use when water testing shows pH below 7.2. Signs of low pH include:

• Eye and skin irritation

• Corroded metal components

• Surface damage to plaster or concrete

• Rapid chlorine loss

Directions for Use

1. Test pool water to confirm pH is below 7.2.

2. Add 100g per 10,000 litres (approx. 2,200 gallons).

3. Sprinkle directly over the pool surface or pre-dissolve in a bucket for best results.

4. Run pump for 2–6 hours.

5. Retest and repeat as needed until pH reaches 7.2–7.8.

You can typically swim after 20–30 minutes, though waiting one full filter turnover (4–6 hours) is recommended.

Proper pH balance is the foundation of safe, sparkling pool water. Choose the right size of pH Up for your pool and keep your water comfortable, chlorine-efficient, and equipment-protected all season long.
