The Ruthenium Problem: Why Salt Cells Are Getting More Expensive - Mondays

Send us Fan MailThis week on Mondays Down Under, Lee, Shane, and Nick sit down with Lee from AIS Water for a fascinating deep dive into the world of saltwater chlorination, chlorinator cells, and the rare-earth metal quietly impacting pool owners across the globe: ruthenium.AIS Water has spent more than three decades focused exclusively on saltwater chlorination, manufacturing everything from residential chlorinators to massive commercial systems used around the world. Lee shares insights from both the Australian and international markets while explaining why chlorinator replacement cells have become significantly more expensive in recent years.The conversation explores how ruthenium—a critical component used in chlorinator cell coatings—has skyrocketed in price due to global supply constraints, geopolitical instability, increased demand from electronics and AI data centers, and reduced mining output. What once cost around $400 USD per ounce now costs more than $1,600 USD per ounce, creating major challenges for manufacturers and consumers alike.The team discusses:Why ruthenium is essential for modern reverse-polarity chlorinator cellsWhether alternative materials could eventually replace rutheniumThe real reasons some chlorinator cells last 10+ years while others struggle to survive warranty periodsHow manufacturers balance quality, longevity, and rising production costsWhy reverse-polarity technology changed the industry foreverThe differences between older mesh-style cells and modern flat-plate designsHow coating consistency impacts chlorine production and cell lifespanWhy AIS continues to prioritize long-term durability over lower-cost shortcutsThe discussion also ventures into water chemistry and operating conditions that dramatically affect chlorinator performance and longevity. Lee explains how low salt levels, improper testing methods, reverse-polarity frequency, phosphates, water temperature, and flow rates can all influence chlorine production and shorten cell life.Listeners will learn:Why running low salt levels can reduce cell life by thousands of hoursThe difference between chloride testing and conductivity-based salt readingsWhy TDS and actual salt levels are not the same thingHow cold water impacts chlorine generationBest practices for winter chlorinator operationWhy some chlorinators produce exactly what their labels claim while others may notThe importance of understanding chlorinator output ratings and testing standardsThe episode also touches on emerging wellness trends, including cold plunges and hot-cold therapy pools, and the unique challenges these environments create for saltwater chlorination systems.Whether you're a service technician, retailer, builder, or simply someone who wants to better understand what is happening inside a saltwater chlorinator, this episode offers a rare behind-the-scenes look at the science, engineering, and economics driving one of the most important pieces of equipment in modern swimming pools.Got questions about saltwater chlorination, chlorinator cells, phosphates, magnesium chloride, or pool chemistry? Let us know and we may bring Lee back for a future episode.Talking Pools Podcast – Mondays Down UnderBecause sometimes the most important thing in your pool isn't what you can see—it's what is happening on a microscopic layer of ruthenium-coated titanium.#SwimmingPools #PoolService #SaltWaterPools #PoolIndustry #PoolChemistry #TalkingPoolsPodcast #AISWater #PoolProfessionals Support the showThank you so much for listening!
