Aquacheck Yellow Test Strips (Chlorine)

Tests for Free Chlorine, Total Hardness, pH and Total Alkalinity

50 strips per bottle

Just dip an AquaChek Yellow strip in your pool or spa water for one second, and remove it immediately and you get test results in seconds! To keep your pool at its best, test at least twice a week, and test your spa before each use.

It's also a good idea to write down your results each time you test, so you can track your chemical levels with ease.
