How to Test Chlorine
- 1). Turn on your pool's water pump, if you haven't already, and allow the water to circulate for between five and 10 minutes. This will allow the existing chlorine to properly disperse throughout the pool water.
- 2). Dip one of the chlorine test strips, and dip it into your pool water. Hold it there until it changes color. This could take several seconds to a minute.
- 3). Shake off any surplus water from the test strip, and let it sit for 30 seconds.
- 4). Compare the color the test strip turned into with a color on the test strip's chart, which should have come in its packaging or even on the packaging. The corresponding colors will tell you the chlorine level. For example, if the strip turned blue, and the strip's chart indicates that blue represents a chlorine level between 2.0 and 3.0, then that is your pool water's chlorine level.
- 5). Repeat Steps 2 through 4 with another test strip to ensure you get the same results.
