AquaChek® Chlorine Test Strips make it easy to monitor key water levels, testing for chlorine, pH, total alkalinity, and cyanuric acid (stabilizer). They’re ideal for customers who use chlorine as their primary sanitizer in a pool or spa. These strips also include a cyanuric acid (stabilizer) test—especially important for outdoor pools and hot tubs, where UV rays can break down chlorine more quickly. How to use: Dip one AquaChek Yellow strip into your pool or spa water for 1 second, then remove immediately and compare results. Includes: 50 test strips
