During hyperchlorination for diarrhea, you must confirm that the filtration system is operating while maintaining the proper free chlorine concentration and pH. Running the filter ensures continuous circulation and contact of the water with the disinfectant, while keeping the free chlorine at the elevated level and the pH in the effective range maximizes disinfection. Draining the pool, treating only surface water, or removing chlorine after a short period do not align with the required approach; the goal is sustained disinfection over the specified contact time with continuous filtration.
