Common questions
What if I am not satisfied?
We think that once you try an EcO, you’ll love it! However, if you’re not completely satisfied, don't worry: we offer a 30-day money-back guarantee.
Can I use the monitor with non-iopool branded products?
Yes. However, for the best experience, we recommend using the iopool brand because our recommendation engine is designed around our own products.
What is the lifespan of the probe?
EcO has a lifespan of 2 years, after which you will have to order a replacement module including a new battery and sensors. Buying this module extends the warranty for two more years.
What is the warranty period for the probe?
The EcO probe is guaranteed for 2 years from the date of purchase.
Do I need to pay for any subscription?
No. You can access all functionality without any subscription, including customer assistance by chat.
Can I access my data around the world?
This is possible with the iopool Bluetooth / Wi-Fi Gateway included in the EcO Start and Connect pack only. By default, EcO uses Bluetooth Low Energy (BLE) technology to send data to your smartphone, so you must be near the pool (approx. 30 feet).
What are the water parameters monitored by the probe?
EcO monitors
- Water temperature;
- Disinfection capacity (Redox capacity, ORP);
- pH (hydrogen potential).
Our algorithm derives 3 additional parameters from the initialization process:
- Hardness of the water;
- Alkalinity of the water;
- Amount of stabilizer (cyanuric acid level).
Have additionnal question?
Refer to the dedicated section of our FAQ or contact us via in-app support or on the website.
Warning
- After initialization, don’t remove the EcO from the water. See this article for more information;
- If you have a bromine pool, never follow the "add chlorine" recommendation of the app. For more information, see this article.
