Pool Alkalinity: Essential for Healthy and Crystal Clear Water

A healthy and clear pool begins with proper water balance. Alkalinity is the basis for a stable pH level and prevents problems such as corrosion, scale and cloudy water. By maintaining your alkalinity, you ensure that chlorine works effectively and your pool remains comfortable for swimmers. Find out all about the importance of alkalinity and how to easily correct it with the right products here.

What is alkalinity in swimming pools?

Alkalinity is the buffer that helps keep the pH level of your pool water stable. Properly balanced alkalinity prevents fluctuations in pH, keeping pool water comfortable and safe for swimmers and preventing damage to pool equipment.

Why is alkalinity important?

• Stabilizes pH levels and prevents large fluctuations
• Protects pool materials from corrosion and scale build-up
• Improves the effectiveness of chlorine for better disinfection
• Prevents cloudy water and helps maintain clear water quality

How do you measure and correct alkalinity?

The ideal alkalinity for pool water is between 80 - 150 ppm. If the value is too low, it can cause corrosion of metal parts, damage to the pool liner and an unstable pH. Too high an alkalinity, on the other hand, can cause scaling and cloudy water.

To maintain alkalinity, specific pool products are available:

• Alkalinity Increaser (Sodium Bicarbonate) - Increases alkalinity and stabilizes pH
• Alkalinity reducer (Sulfuric acid or pH Minus) - Used to correct excessive alkalinity
