In this episode, Rudy Stankowitz discusses oxidation reduction potential (ORP) and how it is used to gauge the effectiveness of water treatment in swimming pools. He explains that ORP measures the water's ability to oxidize or reduce substances, which directly relates to the pool's ability to keep contaminants at bay. Rudy also explores the factors that can influence ORP readings, such as chlorine levels, pH, cyanuric acid, temperature, organic contaminants, total dissolved solids (TDS), and other chemicals in the water. He emphasizes the importance of regularly testing water chemistry and using automated ORP sensors and controllers for continuous monitoring and adjustments. In this conversation, Rudy discusses the importance of ORP (oxidation reduction potential) testing in maintaining water quality in pools. He explains how ORP fluctuates throughout the day and provides tips on timing chemical adjustments to maintain consistent water quality. Rudy also highlights the different approaches to ORP for indoor and outdoor pools and the benefits of using modern pool management systems with ORP control features. In the second part of the conversation, Rudy explores the concept of finding an underserved niche in the pool service industry. He explains the benefits of specializing in a specific area and offers tips on identifying and serving an underserved niche. Rudy emphasizes the importance of market research, understanding customer needs, and continuously innovating to stay ahead in the niche market.
