Maintaining a pool or spa goes beyond just adding chlorine and running the filter. One of the most critical parameters to monitor is pH. Often underestimated, pH balance is key to water quality, equipment durability, and swimmer comfort. Here's why.

1. What Is pH?

pH (potential hydrogen) measures the acidity or alkalinity of water on a scale from 0 to 14:

• A pH < 7 means the water is acidic.
• A pH > 7 means the water is alkaline.
• The ideal pH for pool or spa water is between 7.2 and 7.6.

2. Balanced pH = Healthier Water

When pH is within the ideal range:

• Disinfectants (like chlorine or bromine) work at full efficiency.
• Water stays more chemically stable.
• There's a much lower risk of algae, bacteria, or cloudy water developing.

3. Unbalanced pH Can Damage Your Equipment

Too high or too low pH can:

• Corrode metal parts, pumps, seals, or filters.
• Reduce the lifespan of your sensor and electronic components.
• Cause scaling (if pH is too high) or make the water aggressive (if too low).

4. pH Directly Affects Swimmer Comfort

Incorrect pH can cause:

• Eye and skin irritation.
• Unpleasant odors.
• Cloudy or uncomfortable water.

Balanced water means safer, gentler, and more enjoyable swimming.

5. The Role of the EcO Sensor in Monitoring pH

With the iopool EcO connected sensor, monitoring pH becomes easy and automatic:

• The sensor continuously measures pH levels.
• You receive real-time alerts via the iopool app.
• The app tells you exactly what product to add, and when.

The result: less guesswork, less waste, and balanced water all the time.

Conclusion

pH is the cornerstone of your pool or spa’s water balance. Keeping it in check improves chemical efficiency, protects your equipment, and ensures a better bathing experience. With smart tools like the EcO sensor, managing pH has never been easier.
