How to Raise Pool pH: Complete Guide
Learn how to safely raise pool pH using soda ash or pH increaser. Complete guide with accurate dosage calculations for Australian pools.
Why Raise Pool pH?
Low pH (below 7.2) causes several problems:
- Eye and skin irritation
- Equipment corrosion
- Etching of pool surfaces
- Reduced sanitization effectiveness
Ideal pH range is 7.2-7.6. Use PoolCalculator.com.au to check if your pH needs adjustment.
Step 1: Test Current pH Level
Use a pool test kit or test strips to measure current pH. Read our guide on how to read test strips.
Ideal pH: 7.2-7.6
Action needed if: pH is below 7.2
Step 2: Calculate Required Dosage
Use PoolCalculator.com.au to calculate exact amount needed:
Dosage Guidelines:
- 50,000L pool: 150-200g soda ash raises pH by 0.1
- 30,000L pool: 90-120g soda ash raises pH by 0.1
- 75,000L pool: 225-300g soda ash raises pH by 0.1
Step 3: Pre-dissolve Soda Ash
Pre-dissolve soda ash in a bucket of pool water before adding to pool. This prevents cloudiness and ensures even distribution.
Step 4: Add to Pool
- Turn on pool pump - Ensure circulation is running
- Pour slowly - Add dissolved soda ash to deep end
- Walk around perimeter - Distribute evenly while pouring
- Never mix chemicals - Add separately from other chemicals
