Pool Shocking and Breakpoint Chlorination, Explained

Breakpoint chlorination is a key concept in pool chemistry. In May 2017, we published a two-part article about pool sanitizers. In part one we compared different chlorine types, and their pros and cons. This article dives deeper into the science of chlorination. We explore the difference between breakpoint chlorination and hyperchlorination (shocking). What is breakpoint […]

Difference between Total Alkalinity and Carbonate Alkalinity

The LSI requires knowing the carbonate alkalinity of pool water…but most pool test kits measure total alkalinity. What’s the difference? Carbonate Alkalinity can be calculated from Total Alkalinity…if the pH is known Let’s start with a quick recap of what alkalinity actually is. Total alkalinity is a measurement of dissolved alkaline substances in the water. […]

How Orenda enzymes actually work

  How Orenda enzymes actually work Orenda enzymes CV-600 and CV-700 are beautifully simple products to use. Just pour them in the pool as directed, and they will do the rest. This article will explain how enzymes work, but more importantly, the differences between enzyme digestion and traditional oxidation. Oxidation vs. Digestion Oxidation Chlorine, Bromine, […]

Phosphates affect chlorine efficiency

Phosphates affect chlorine efficiency, and this article will explain why. Phosphates are quite the buzz word in the pool business these days. Yet in our travels and conversations, few people actually know why it is beneficial to rid your pool of them. It’s just common knowledge that it’s good to address them–you know, for the benefit […]

Calcium Scale ≠ Calcium Hydroxide crystals

  Have you ever encountered the problem of “calcium scale that keeps coming back”? Has it been impacting your pool business? Are you sure you have diagnosed the problem correctly? Because it’s easy to mistake calcium hydroxide crystallization for carbonate scale. This is a common problem, especially in colder climates, so we decided to share what we know, and […]

Pool filter channeling – causes, symptoms, and how to fix it

  Filter Channeling is a problem Seasoned pool operators know the triad of great pool water: filtration, circulation and chemistry. Without effective filtration, there will always be problems… and filter channeling undermines filtration. Filter channeling is a condition when water finds its way through pockets in the filter media, and avoids being filtered. Water finds […]

How to use the Orenda App: Dosing Calculator + LSI

  Need an accurate pool chemistry Dosing Calculator? Yes, there’s an App for that. Pool operators and service professionals have a tough job to do. Pool owners expect their service experts to know exactly what to do, and when to do it. We created the Orenda App dosing calculator to help ease that burden. Our dosing […]

Pool sanitizers, Part 2: Chlorine alternatives

Pool Sanitizers, continued…Chlorine alternatives In part 1, we discussed the various types of chlorine, and why a residual pool sanitizer is essential for a safe, healthy swimming pool. This article will cover chlorine alternatives. Again, this is taking a vast array of information and simplifying it for you to read… as always, if you want […]

Different types of pool sanitizer, Part 1: Chlorine

A good pool sanitizer is essential to a healthy, safe swimming pool Even with the latest and greatest technology in the swimming pool industry, the need for a residual sanitizer in the water remains essential. A residual of pool sanitizer is the first line of defense against germs, as its primary function is disinfection. The secondary […]

Cold water is more corrosive and can etch plaster

  Cold water lowers the LSI and makes pool water more corrosive Remember the Langelier Saturation Index (LSI)? It’s an index that accounts for temperature, pH, alkalinity, calcium hardness, stabilizer and TDS. We have test kits that test for all that stuff…. but how often do you actually test water temperature? Oh, you don’t? Until we understood the […]
