POOL CHEMICALS

✅ Key Water Balance Parameters (AS 3633-1989)
1. pH Level

• Operating Range: 7.0 to 7.8

• Recommended Range: 7.2 to 7.6

• Fibreglass Pools: SPASA recommends 7.0 to 7.2 2. Total Alkalinity

• Recommended Range: 60 to 200 ppm

• Typical Target: 100 to 120 ppm

3. Calcium Hardness

• Recommended Range: 80 to 500 ppm

• Purpose: Prevents corrosion (low levels) and scaling (high levels)

4. Free Chlorine

• Recommended Range: 1.0 to 3.0 ppm

• Purpose: Effective disinfection and swimmer

5. Cyanuric Acid (Stabiliser)

• Recommended Range: 30 to 50 ppm

• Purpose: Protects chlorine from UV degradation

⚠️ Why Water Balance Matters

• Swimmer Comfort: Prevents skin irritation and red eyes.

• Sanitiser Effectiveness: Ensures chlorine works efficiently.

• Equipment Protection: Prevents corrosion and scaling.

• Aesthetic Appeal: Maintains clear and inviting water

🧪 Testing and Adjustment Tips

• Regular Testing: Use reliable test kits or consult a SPASA-accredited pool shop.

• Adjustments: Add acid to lower pH; use bicarbonate to raise alkalinity.

• Maintenance: Regularly monitor and adjust levels to maintain balancE
