Eric says goodbye in his last episode before taking the helm as Executive Director at Watershape University.

Eric talks about the difference between the valence states of the chlorine atom. Cl+ is different from chlorides, which are Cl-. Chlorides are inert, but they can be recharged into chlorine gas with a salt chlorine generator, and they also interfere with stainless steel's chromium oxide layer, helping chlorine corrode it.

Terry, Miguel and Eric discuss the devastating wildfires in greater Los Angeles, and what our industry can do about it to help those directly affected.

Terry invites Jim Lauria, the VP of sales for Mazzei Injector Company, onto the podcast. Jim hosts a podcast called "Water we talking about?" Jim caught our attention with an article about how Leonardo Da Vinci's fascination with water. Jim has a passion for telling water's story, and so do we.

Expanding on last episode (164), Eric talks about a few scenarios where a pool heater can both corrode AND scale. There are several reasons beyond water balance that can cause corrosion, and chasing pH usually makes things worse.

Thanks to the help of a metallurgist, Eric does his best to explain metal corrosion in a simplified way. It's an electrochemical reaction where electrons are transferred between an anode and cathode.

Eric discusses three constants that pool owners and professionals can always rely on. Like them or not, they have always been there, and they are not going away.

Eric sits down with Mike Collins from TenJam pool furniture to discuss scale formation and scum lines on plastic pool furniture.

Eric is joined by Teresa Berry to discuss the new Orenda Calculator integration with PaythePoolman, a pool business software that has been helping pool pros since 2015.

Eric reflects on the horrific devastation from Hurricanes Helene and Milton, the raw power of flood water, and a reminder that swimming pools are just samples of domesticated water. It's unwise to fight it.

Joe Sweazy joins the show to talk about cyanuric acid (CYA) testing and its limitations.

Eric and Jarred dive deep on calcium phosphate scale, aka hydroxylapatite, and how it differs from calcium carbonate.

Jarred returns to the podcast to talk about dry weight vs. liquid volume, and how it relates to pool chemicals. We also discuss chlorine product percentages and what they mean.

Eric goes in depth on closing the pool for the winter (winterization), what the fundamental objectives are, and why.

Terry Arko joins the show once again to talk about non-chlorine shock, specifically the oxidizer product called potassium peroxymonopersulfate, aka monopersulfate or just MPS.

Terry Arko joins the show to explain why foam occurs in hot tubs and pools, what defoamer products are, how they work, and some better alternatives that don't contribute to the long-term problem.

Eric answers a customer's question about vacation rental properties and their unpredictable bather loads and temperature swings.

Eric walks through the impact that pool covers have on pool chemistry throughout the season. In short, they block dilution and the off-gassing of CO2.

Eric explains a global phenomenon that most of us are probably unaware of. 182 million tons of dust from the Sahara Desert blows across the Atlantic ocean, and our ecosystem depends on it...mainly because that dust is loaded with phosphorus. How does that dust impact pools in the western hemisphere?

Eric briefly updates the audience on the Orenda App projects and the new Watershape University chemistry course being created. This would have been an Olympic preview, but due to technical difficulties with our last guest, we will have to re-record after the Olympics.
