Eric demonstrates why column-pouring undiluted acid into a pool is a bad idea. Food coloring and muriatic acid show the acid going straight to the floor.

Eric, Terry and Jarred address a class that not-so-subtly calls us out (but not by name) for pushing "FALSE" information to the pool industry and beyond. Their class "debunks" 9 myths, which are each discussed in this episode.

Eric dives deep into Oxidation-Reduction Potential and why it's used in swimming pools. How is ORP measured, and what does it tell us? What affects it?

Terry Arko joins Eric to talk about the pH impact of each chlorine product used in swimming pools. What is actually going on when these chlorine products dissolve in water?

Eric and Jarred explain the Orenda Calculator's LSI formula and the research trail behind it, citing all the papers that have evolved the LSI formula into what it is today, and why it is slightly different than the LSI reference chart.

Eric and Jarred visit with people while sitting at our trade show booth in Atlantic City at the 2024 Northeast Pool and Spa Show.

Eric outlines how to manually put water in its natural state so that both water balance and water quality can be maintained.

When looking at a pool chemical product label, what do the percentages actually mean? Eric explains these percentages and how molecular mass is converted into practical weight (g/mol) are calculated and compared.

Eric and Jarred recap the 2023 Int'l pool and spa show, the Pool Nation Awards, and do what they can when they can to reach 200 listeners by the end of the year.

Eric and Jarred revisit the most frequently asked questions of 2023, and look forward into 2024.

Eric explains two lesser-known relationships between chlorine and alkalinity.

Eric outlines everything done to his fixer-upper pool this year. Ever since the green pool cleanup was completed on May 14, physics has taken control of the water, making it incredibly reliable and predictable. Every chemical and action has been documented throughout the year, so Eric explains exactly how he ruled his pool.

Eric and Dennis discuss commercial pools and the common issues Dennis has observed in them over the last several decades. Dennis shares how Orenda products and the app have helped him and his customers in the field.

In this episode, we honor the life and work of Derek A. Ingram, one of the few architects of the technology used to clear out chloramine pollution in indoor swimming pools. Without Derek's work, tens of thousands, if not hundreds of thousands of swimmers would still be exposed to harmful chloramines. Tragically, Derek recently passed away after a 20-month battle with ALS. In this episode, we are joined by Derek's father, Dennis Ingram, a veteran commercial pool builder and service...

Closing out our 4-part series on chemical conflicts, Eric discusses metal and stain removers, SC-1000 and chlorine, sequestering agents and phosphate removers, and enzymes vs. polymers and other products.

Terry and Eric continue the conversation about chemical conflicts, and in this episode they focus on chlorine alternatives. Biguanides, hydrogen peroxide, bromine, and secondary systems.

Terry and Eric discuss different types of algaecides and the byproducts they leave behind. Spoiler alert, chlorine conflicts with all of them.

After a borderline-grammy-worthy intro, Eric discusses the volatility of all different chlorine types, and how they should and should not be used, handled and stored. This is the first of a multi-episode series on chemical conflicts.

We are joined by Dr. Darla Goeres, the world's leading biofilm researcher and expert. Dr. Goeres defines biofilms, explains why they matter and what we can do to prevent and remove them in recreational water.

Does calcium hardness still matter for fiberglass and vinyl liner pools? Does the LSI still matter? Tyler and Eric discuss the importance of both, especially in non-cement pools. Chalky white discoloration of fiberglass pools and fading vinyl liners are just some of the symptoms of not having enough calcium hardness to balance the LSI year-round.

Terry schools Eric and Jarred on green and yellow algae, based on research and wisdom he has obtained experientially. Jarred piles on and complains about brushing...or something.

Eric and Jarred talk about "black algae", which is technically a cyanobacteria. They cover what black algae is, and what you can do to remove it and prevent it from coming back.

Eric talks about SC-1000 and why it reduces free chlorine on its initial purge dose, and what you can do about it. The episode also covers the comparison between chelating agents like SC-1000 and sequestering agents.

Does your pool have enough calcium hardness in it? Most pools do not. And yet, calcium is the bedrock of water balance. Eric explains what calcium is and why it's so important.

Terry Arko and Eric discuss bromine chemistry and how it differs from chlorine. They talk about bromine byproducts like bromamines, harmful trihalomethanes and even-more-harmful bromates.
