In order to test your pool water, you’ll need some pool water test strips. The same test strips can be used for testing the water of a hot tub if you have one. Most pool water test strips will test your water’s, free chlorine/bromine, total chlorine, cyanuric acid, total alkalinity, and pH level. While that might sound daunting, test kits make it easy to understand the test results using a colour-coded chart. The testing process takes less than a minute.
