EcO Start Salt – Smart Water Analyzer for Saltwater Pools
EcO Start Salt is a connected water analyzer designed for swimming pools and spas treated with salt chlorination. It automatically monitors three essential water parameters — pH, ORP and water temperature — and sends the results to the iopool app, where they are translated into clear, personalized maintenance recommendations.
Unlike the standard EcO Start, EcO Start Salt is specifically designed for water treated with a salt chlorinator.
Important: EcO Start Salt does not measure salinity directly. It monitors water balance and disinfection performance, while the salt concentration should be checked separately with salt test strips or an appropriate salinity tester.
Why saltwater pools still need water monitoring
A saltwater pool is not maintenance-free. The salt chlorinator converts dissolved salt into chlorine, but it does not automatically keep every water parameter balanced.
In particular, salt chlorination can contribute to a gradual increase in pH. When pH moves outside the recommended range, chlorine becomes less effective and problems such as cloudy water, scale or reduced disinfection efficiency can appear.
Manual tests provide a useful snapshot, but they require regular intervention and can lead to approximate dosing. EcO Start Salt makes monitoring easier by automatically following the parameters that change most frequently.

How EcO Start Salt works
Installation only takes a few minutes.
Place EcO Start Salt in your pool or spa and connect it to the free iopool app. Its sensors automatically monitor:
-
pH;
-
ORP, or Oxidation-Reduction Potential;
-
water temperature.
The app interprets these readings and tells you when an adjustment may be needed and how much treatment product to add.
EcO Start Salt communicates through Bluetooth Low Energy. When you are close to your pool, your smartphone can retrieve the latest data.
For remote monitoring from anywhere, choose EcO Start Salt + Connect or add the compatible cOnnect Bluetooth/Wi-Fi gateway.
What does EcO Start Salt measure?
| Parameter | Automatic monitoring | What it tells you |
|---|---|---|
| pH | Yes | Acidity and alkalinity balance of the water |
| ORP / Redox | Yes | Oxidizing and disinfection capacity of the water |
| Water temperature | Yes | Helps interpret treatment needs |
| Salinity / salt level | No | Check separately using salt strips or a suitable tester |
| Free chlorine in ppm | No | Periodic manual test |
| Stabilizer / CYA | No | Periodic manual test |
| Alkalinity | No | Periodic manual test |
| Water hardness | No | Periodic manual test |
The included 6-in-1 test strips complement EcO Start Salt for parameters that do not require automatic monitoring.

Features designed for easier pool maintenance
Three essential sensors
EcO Start Salt combines pH, ORP and temperature monitoring in one compact floating device.
Personalized iopool recommendations
The app converts measurements into understandable actions instead of simply displaying technical values.
Bluetooth connectivity
EcO Start Salt communicates locally using Bluetooth Low Energy.
Optional remote monitoring
Add cOnnect or choose EcO Start Salt + Connect to send pool data through your home Wi-Fi and consult it when you are away.
Replaceable components
The current EcO generation allows the battery and sensor module to be replaced, helping extend the useful life of the product.
No subscription
All standard iopool app features are available without a recurring subscription.
Who is EcO Start Salt for?
EcO Start Salt is particularly useful for:
-
family swimming pools using salt electrolysis;
-
spas treated with a compatible salt system;
-
pool owners who regularly need to correct pH;
-
beginners who want help interpreting water chemistry;
-
users who want to reduce manual water testing;
-
owners of second homes who combine EcO Start Salt with cOnnect for remote monitoring.
Does EcO Start Salt measure salinity?
No. EcO Start Salt does not directly measure the concentration of salt in ppm or g/L. It automatically monitors pH, ORP and water temperature. Salt concentration should still be checked separately using salt test strips or another salinity tester according to the recommendations of your salt chlorinator manufacturer.
Why test a saltwater pool if the chlorinator already produces chlorine?
A salt chlorinator produces chlorine from dissolved salt, but it does not automatically maintain the overall water balance. pH can change, disinfection efficiency can vary and other parameters still require attention. Monitoring pH and ORP helps you understand whether the water conditions remain suitable for effective disinfection.
Is ORP the same as free chlorine?
No. ORP, or Oxidation-Reduction Potential, is measured in millivolts and indicates the oxidizing or disinfecting capacity of the water. Free chlorine is a concentration measured in ppm or mg/L. The two are related, but an ORP reading is not a direct measurement of the amount of free chlorine present.
Why choose EcO Start Salt?
EcO Start Salt is designed specifically for users who treat their pool or spa with salt.
| EcO Start | EcO Start Salt | EcO Start Salt + Connect | |
|---|---|---|---|
| pH, ORP and temperature | Yes | Yes | Yes |
| Designed for saltwater | No | Yes | Yes |
| Bluetooth monitoring | Yes | Yes | Yes |
| Remote Wi-Fi monitoring | No | No | Yes |

FAQ
How does a connected saltwater pool analyzer work?
EcO Start Salt floats in the pool and automatically measures pH, ORP and temperature. The iopool app receives the readings and converts them into personalized maintenance recommendations.
Does EcO Start Salt measure the salt level?
No. Salinity must be checked separately with salt test strips or a compatible salinity tester.
Do I still need test strips?
Yes, occasionally. EcO Start Salt automatically monitors the parameters that vary most frequently, while test strips remain useful for parameters such as stabilizer, alkalinity and hardness.
What is the difference between EcO Start and EcO Start Salt?
EcO Start Salt is designed for pools and spas treated with salt chlorination. The standard EcO Start should not be used in salt-treated water.
Does EcO Start Salt control my salt chlorinator?
No. EcO Start Salt analyzes the water and provides maintenance recommendations. It does not directly control or automatically adjust the output of your salt chlorinator.
Can I monitor my pool when I am away?
EcO Start Salt uses Bluetooth by default. For remote monitoring through the internet, use EcO Start Salt + Connect or add a compatible cOnnect gateway.
Can EcO Start Salt be used in a spa?
Yes, it can be used in compatible salt-treated pools and spas.
Is there a subscription?
No. The iopool app can be used without a recurring subscription.
