Abstract: A kit for determining if a shock treatment is required for a water source may comprise a test strip having at least two chemically treated test areas. One of the areas is responsive in color to a concentration of free chlorine in the water and another test area is responsive in color to a concentration of total chlorine in the water. A chlorine indicator scale may be provided on a substrate, such as a label, and comprises a plurality of pairs of colored indicia and each pair of colored indicia representing a color pattern indicating a concentration, or range of concentrations, of total chlorine and free chlorine in the water. An alphanumeric designation may be provided adjacent to each pair of indicia indicating whether a shock treatment is required for the water source based on a color pattern the associated indicia pattern.
