The water chemistry and bactericidal chemical concentrations shall be maintained within the parameters as established in 410 I.A.C. 6-2.1. Where the concentration of combined chlorine is greater than 0.50 mg/l (ppm), the swimming pool shall be superchlorinated or otherwise treated in a manner to oxidize and reduce the concentration of combined chlorine. No harsh or irritating chemical in concentrated form shall be added manually and directly to the water of any swimming pool except under emergency conditions. Should it be necessary to add any harsh or irritating chemical in concentrated form directly into the water of any swimming pool, use of the swimming pool shall be terminated until a time as the chemical is dissolved completely in and is diffused thoroughly throughout the swimming pool. The broadcasting or manual application of chemicals to maintain a disinfectant residual or pH is prohibited except as may be required to superchlorinate the swimming pool. Under no conditions may superchlorination or manual adjustment of pH occur while the swimming pool is in use by swimmers.
