My test strips and the app do not agree

If your test strip and the app show different readings, here is how to figure out which one to trust.

1. Test your water with a fresh test strip and compare it to the reading in the app. If you need new strips, you can order LaMotte Insta 3-Way Test Strips on ArcticSpaStore.com.
2. If the strip and the app are close, the sensor is working and you just need to keep adjusting, for example add more Adjust Down if your pH is high.
3. If the strip reading is very different from the app, the sensor may have an issue. Contact us and our service team will help.

If you run into a situation where your app and your test strips do not agree, make sure that you have fresh test strips, that they're not old or have deteriorated from being in the sun or exposed to moisture. And then do another test strip reading. If the app and the test strips are not somewhat close, then it is possible to calibrate the readings on the app if you have a 2020 or newer spa. If it is older, if it's 2019 or older, it is not possible to calibrate, and you would need to replace the probe. You can order a replacement Probe for Onzen Spa Boy/pH on ArcticSpaStore.com.

Let us know if you need anything else. Happy Hot Tubbin'!
