## Questions & Answers

**Q: How does the WaterGuru SENSE Work?**
A: The WaterGuru Sense S2 installs in your skimmer and uses optical tech to measure FC, pH, TA, CYA, and CH daily. The app shows your levels and provides custom advice based on your pool type, size, and chemicals to keep water balanced.

**Q: What’s in the Box?**
A: Includes the WaterGuru Sense S2, a C5 Cassette, 4 C batteries, a float ring for spas or above-ground pools, and a Quick Start Guide to help you install and get set up in seconds—everything you need to start smart pool monitoring right away.

**Q: Do I need Wi-Fi access near my pool for the WaterGuru SENSE to work?**
A: Yes. You will need Wi-Fi access at the pool area where the WaterGuru SENSE will be installed.

**Q: WaterGuru Pool Skimmer Monitor vs. Floating Pool Monitor – What’s the Difference?**
A: Floating monitors can drift, get damaged, or pose safety risks in active pools. WaterGuru Sense sits safely in your skimmer, out of the way, and delivers more stable, accurate readings by staying in constant water flow—no interference, no hassle.

**Q: Pool Test Strips vs. WaterGuru Chemical Monitoring?**
A: Test strips are time-consuming and often inaccurate. WaterGuru Sense sits in your skimmer and uses smart optical sensors to test key chemical levels. View results in the app with personalized advice—no guesswork, color matching, or manual testing.
