                                     In this example, the amount of 70% chlorine compound required for
                                     166 tons of water at 50 parts per million is 11,869.0 grams or
                                     11.87 kilograms.

                               The Available Chlorine in Compounds table lists the various chlorine
                               compounds and the amount of the compound  required in grams per liter of
                               water to produce a solution containing 100 ppm of  chlorine. The 100-ppm
                               chlorine solution should be applied as outlined in this  manual.
