What this episode covers

David Watson, a 40-year pool industry veteran in Perth, Australia joins the show to discuss his findings about using carbon dioxide for pH management, and some fascinating discoveries about Total Dissolved Solids (TDS). And he may have had something to do with the arbitrary industry-standard limit of "1500 ppm above tap water" for TDS.
