Which EcO should you choose? A guide to finding the perfect sensor for your pool or spa

Choosing the right sensor to monitor and maintain your pool or spa water is essential to ensuring clean and balanced water. At iopool, we offer two EcO models:

• EcO Salt, ideal for salt-treated pools, but also compatible with chlorine and bromine.
• EcO Chlorine, designed for pools and spas using chlorine or bromine.

So, which EcO is right for you? Here’s a guide to help you make the best choice.

1. EcO Salt vs. EcO Chlorine: What's the Difference?

The key difference between these two sensors lies in their compatibility with water treatments.

*Note: Bromine is only available in France.

2. Why Choose EcO Salt?

EcO Salt is the most versatile sensor. Even though it is designed for saltwater pools and spas, it is also compatible with chlorine and bromine.

• If you have a saltwater pool, you must choose EcO Salt.
• If you have a spa, we highly recommend EcO Salt, as salt treatment is more common for spas.
• If your budget allows, EcO Salt is a future-proof choice, especially if your needs may change over time.

In short, EcO Salt works with all treatments, while EcO Chlorine is limited to chlorine or bromine pools and spas.

3. Why Add a Gateway?

The iopool gateway is a WiFi relay that allows you to transmit your EcO sensor data to the iopool app, even remotely.

Why is it recommended?

• It extends signal range, especially if your pool or spa is far from your home.
• It provides access to your data anytime, anywhere, for real-time monitoring.
• It offers extra convenience: no need to be near the pool to check your water status!

If your pool is located far from your house or if you want continuous access to your data, the gateway is the perfect add-on to maximize your EcO sensor’s efficiency.

4. Which EcO is Best for Your Pool or Spa?

The right choice depends on your pool type and treatment.

• Do you have a spa? → We recommend EcO Salt, as salt treatment is more common for spas.
• Do you have a pool? → Choose based on your treatment:

• • Saltwater pool → EcO Salt (mandatory).
  • Chlorine-treated pool → EcO Chlorine or EcO Salt (both are compatible).
  • Bromine-treated pool (France only) → EcO Chlorine or EcO Salt (both are compatible).

➡ What about the gateway? No matter your setup, the Gateway is always a great option for a more comfortable and reliable connection, especially if your pool is far away.

Conclusion

Choosing the right EcO sensor depends mainly on your pool or spa’s treatment type. If you use salt, EcO Salt is a must, and if your budget allows, it’s the most versatile choice.

Finally, adding a gateway is highly recommended for those who want easier and more efficient monitoring of their pool or spa.
