AquaChek Cyanuric Acid now features an improved test for Cyanuric Acid. It's faster and easier to use than liquid test kits.

• This strip allows you to test Cyanuric Acid up to 300 ppm (mg/L), a higher level than any other test available (including liquid kits)!
• This new Cyanuric Acid test works under a wide range of pool conditions: in pH between 7.0 and 8.4, and in Total Alkalinity at or below 240 ppm.
• The improved chemistry offers enhanced colors for greater color distinction and easier readability.

Compare our test results against your favorite liquid kit. Just dip an AquaChek Cyanuric Acid strip in pool or spa water for one second and remove it immediately. You get test results in seconds!
