What is ICO Pool?

ICO Pool is a smart connected water analyzer that monitors your pool water quality 24/7. It measures pH, ORP (oxidation-reduction potential), and water temperature every hour. For salt water pools, ICO also analyzes TDS (Total Dissolved Solids). Using advanced algorithms, ICO anticipates water quality changes and provides personalized recommendations through the mobile app, ensuring you add the right products in the right amounts at the right time.

Smart Pool Maintenance Made Simple

ICO is revolutionizing pool maintenance by making it crystal-clear and effortless. By continuously monitoring your pool's vital parameters and connecting to weather data, ICO helps maintain perfect water quality while minimizing chemical usage. The system takes into account your pool's specific characteristics, including volume and treatment type, to provide tailored guidance.

Features Available on the ICO Application

The ICO mobile app, available for both iOS and Android, offers an intuitive interface with powerful features:

  • Water Index Dashboard: Quick overview of current measurements, water quality status, battery level, and notifications
  • Detailed Analytics: View trends and data by day, week, or month
  • Smart Recommendations: Get personalized maintenance guidance
  • Multiple Pool Management: Easily switch between different pools and spas
  • Remote Monitoring: Share access with family or pool service providers
  • Weather Integration: Anticipates water changes based on weather conditions
  • Customizable Alerts: Set notifications for important parameters

Pool Compatibility

ICO works seamlessly with:

  • All common sanitizer types: Chlorine, Bromine, and Salt Chlorination systems
  • Any pool type: Indoor, outdoor, above-ground, in-ground, or overflow
  • All standard equipment: Compatible with sand filters, variable/non-variable speed pumps, etc.
  • Pool covers and automatic systems

Easy Installation and Maintenance

ICO features a sleek, compact design that integrates perfectly with your pool environment. The device can be placed directly in the pool or skimmer, and its plug-and-play sensors make maintenance simple. The long-lasting rechargeable battery typically needs charging just once or twice per season, and the intuitive app guides you through the setup process.

I wish there was a quick guide for fixing pool levels, like “add chlorine to raise ORP.” That would help a lot.

Very helpful app that goes with the ICO sensor. The info is clear. It would be nice if we could tap “OK” for simple notices (like cold water). Also, when buying a new probe, a small tool for changing it would be great.

I’ve had ICO for 4 years, and now the battery is dead. They offered me 50% off a new one, but it’s already expensive, and new probes cost too much. I’m not happy about it.

I used ICO since 2020, but now it’s broken. The pH sensor won’t calibrate. Customer service offered me 40% off a new one, but that’s still a lot of money.

It works well for water care, but the battery doesn’t last. It’s way too expensive for just a few months of use. They should fix the battery issue.

I replaced parts when I first got it, and now, three seasons later, it’s broken again right after the warranty ended. 419 USD for just three summers is not good. Let’s see if support helps or not.

It’s pretty complete, but there’s no TAC reading, and it keeps telling me to add too much pH minus at first. So I don’t always follow its advice.
