Your Gecko waterlab works best when using Insta-Test6 Plus Test Strips, which can be purchased at your local dealer or on Amazon.
You're also welcome to use any other test strips you may already have by comparing the colored pads to your test strip packaging and entering the numbers directly into the app.
