FROG Test Strips provide the ideal chlorine or bromine range for FROG pool and hot tub products. Since minerals reduce chlorine or bromine use by up to 50%, they need a test strip that shows the correct range of 0.5 to 1.0 ppm for chlorine or 1.0 to 2.0 ppm for bromine. These test strips also test for Total Alkalinity, pH and Total Hardness.
