Description
Deep Blue Pro 3-Way Chlorine test strips provide a quick and easy way to test your swimming pool water. They offer tests for free chlorine, pH and total alkalinity. Simply dip the strip in the water and remove immediately. Hold horizontally for 10 seconds (do not shake excess water from the strip), then compare pH, free chlorine, and total alkalinity (in that order) against the colour chart on the test strip bottle.
