Maintaining perfect pool water isn’t just about chlorine—alkalinity plays a crucial role too. If you’ve ever battled cloudy water, irritated skin, or erratic pH swings, unbalanced alkalinity could be the culprit. For luxury homeowners and holiday rental operators in Essex, understanding pool alkalinity levels is key to preserving your investment and ensuring guest satisfaction.
What Is Pool Alkalinity and Why Does It Matter?
Total alkalinity acts as a buffer for your pool’s pH, preventing sudden spikes or drops that damage equipment and irritate swimmers. Think of it as a shock absorber—when properly balanced (80–120 ppm in the UK), it keeps water chemistry stable, reducing maintenance headaches.
The Consequences of Ignoring Alkalinity
- Low alkalinity (below 80 ppm): Causes corrosive water that erodes pool surfaces and metal fittings
- High alkalinity (above 120 ppm): Leads to scale formation, cloudy water, and reduced chlorine effectiveness
- pH instability: Frequent chemical adjustments become necessary, increasing costs
How to Test and Adjust Your Pool’s Alkalinity
Professional pool cleaners in Essex recommend testing alkalinity weekly with digital testers or test strips. For accurate results:
- Collect water 18 inches below the surface
- Test away from return jets
- Check at consistent times (morning readings are most reliable)
Raising Low Alkalinity
Use sodium bicarbonate (baking soda)—it’s cost-effective and won’t drastically affect pH. Add 1.5 lbs per 10,000 gallons to raise alkalinity by 10 ppm. Always dissolve in a bucket first, then distribute evenly across the pool.
Lowering High Alkalinity
Muriatic acid or sodium bisulfate work best. Add small amounts (following product instructions) near return jets with the pump running. Retest after 4-6 hours—adjustments often require multiple treatments.
