Pool owners can get frustrated with pool service techs when the water doesn't look good, or problems occur. It is understandable, and maybe the service tech is at fault...but then again, maybe they are not. Know the facts of the problems before pointing fingers. Otherwise, you're just stuck with the problem.
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).
The LSI calls for the carbonate alkalinity of pool water...but this is a confusing term. Pool chemistry test kits only measure Total Alkalinity (TA). So what is Carbonate Alkalinity? And how is it different from TA?
Enzymes are made up of proteins and amino acids, and they catalyze certain chemical reactions. Our bodies contain countless types of enzymes that help us process food and other things. Pool enzymes are made to break down and digest non-living organics, which makes water cleaner, and chemicals more efficient.
I got a text from a customer in the Northeast that just finished plastering a pool the week before. The text had a picture in it of a green pool, and it read:
NOTE: This article has been revised from its original version, due to learning more from laboratory results. We still have more unanswered questions about crystals than we have answers. Why do they harden? How many forms are there (we know of at least 3)? Why are some crystals easy to clean up, and others stubborn? What common denominators are involved, beyond cold water and lack of calcium hardness?
Seasoned pool operators know the triad of great pool water: filtration, circulation and chemistry. Without effective filtration, there will be problems... and filter channeling undermines filtration.
When sand filters become overloaded or otherwise compromised, water must still find its way through the filter. The water pressure can eventually force its way around the sand (or a channel through it), creating a new path of least resistance for water to travel. Filter channeling is a problem that almost guarantees cloudy pool water, as the channel itself is like a highway for larger particles to travel and bypass the filter media.
The Orenda App and Orenda Calculator™ are some of the most widely-used tools in the pool industry. Here's an overview on how to use them.
The following is a true story, exactly the way I remember it. Not that I could ever forget my time in that tiny warmup pool...
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 to learn more, we encourage you to research these topics further.
Chlorine is the most popular sanitizer/disinfectant used in swimming pools. This article covers the different types of chlorine and how to use them. We will link out to more in-depth articles for each type of chlorine (eventually).
The vast majority of damage done to a pool occurs during the winter, or initial filling/startup. And not just damage to the the pool plaster, but pool equipment can be corroded too. Etching and corrosion are more likely to happen in cold water than warm. This article will explain, with the help of the Orenda App's LSI Calculator. It's all about the LSI.
