Having a pool built, I teach self-rescue lessons to young children and really do not like chlorine as I am in the water 3-4 hours daily. I am researching chlorine alternatives and wanted some feedback/advice. Anyone have experience with: Green Smart, TechnoPure, Ecosmarte or any other systems that either uses no chlorine or significantly reduces that amount of chlorine? Pool builder offers Nature 2 products and Intellichlor salt generator, but has said they will install whatever I want.
