Tests for Free Chlorine, Cyanuric Acid, pH and Total Alkalinity 50 strips per bottle

Just dip an AquaChek strip in your pool or hot tub water for one second, and remove it immediately. You get test results in 15 seconds.

We recommend to test at each end of a pool a minimum of twice a week, and test your spa before each use. Its also a good idea to write down your results each time you test.

Comes with complete instructions.
