Pool test strip scanner app Pooli makes it easier to know what chemicals to add 

Apologies for any confusion. You can use the Pool Style branded (Hach) strips we sell in our shop in the Pooli app, as well as the following strips available on Amazon: Aquachek 7: amzn.to/3qjpz34 Clorox 6-Way: amzn.to/3CXXzW4 These are the only strips compatible with test strip scanner as we've found the Hach test strips to be the most reliable and consistent. You can find more information on test strip compatibility and instructions on how to use them within the app's testing and scanning features by tapping the ? in upper part of the screen Please let us know if you need any further assistance. Best, Kevin

​@@pooliappWhen manually comparing test strips are you use the color inside the rectangular bar? Because everything else outside of the bar regardless of what is being tested is a shade darker compared to what's inside the bar. Thank you
