Leave It Better Than You Found It

My grandfather has a few rules that go unquestioned and are universally obeyed. One of them is "leave it better than you found it." It could mean the bedroom I'm staying in at their home...or the kitchen after I eat lunch. It also applies to borrowing tools, the car, the tractor, or anything else that does not belong to me. Leave (or return) it better than you found it. A profoundly simple rule to remind us to respect others and their property.

Nitrates, Nitrites and Urea in Swimming Pools

Nitrates, Nitrites and other Ammonia-based compounds can be confusing. This article is our attempt to simplify the science and explain why these things matter. If you're looking for a high-level chemistry lesson, this is not the article for you. But feel free to read some of our sources to get your fix: the CDC, NIH, ScienceDirect, and peer reviewed studies like this and this.

Four Things to do When you Open a Pool with Crystals in it

What are you going to do if you remove a winter pool cover and find calcium crystals in the pool? If you have encountered the winter crystals in the past--and you may have thought it was 'scale'--what did you do in the past? Did it work? This article will outline four things Orenda recommends if you are trying to open a pool with crystals in it.

LSI First. Range Chemistry Second.

What if range chemistry is the wrong thing to focus on when managing water? What if the ranges do not always apply, like in the winter? Theoretically, the textbook ranges for chemistry are ideal. But in reality, that's not always the case. In this article we will explain why we prioritize the Langelier Saturation Index (LSI) first, and range chemistry after that.

Honesty in Water Chemistry Testing

 
 

If you're not testing, you're just guessing

Water testing is too often rushed and overlooked in our industry. A few months ago, I had the opportunity to take the startup certification course for the National Plasterer's Council, hosted by Bel-Aqua. As an employee of Orenda, I work with service techs and plaster companies every week. This course was a wonderful opportunity to soak up information like a sponge, and learn more about the business. Granted, I was not actually supposed to take the course (Orenda was a sponsor of the event, and I am not a service tech), but I was invited to participate.

Pool Chemistry During the Winter

This article aims to shed light on what really goes in a pool that is winterized. When the temperature drops, chemistry changes. Pools must be treated differently in the winter than they are in the summer, You can read our primary article about Proactive Pool Winterization here.

What is Alkalinity?

Alkalinity is one of the primary things measured in water chemistry. But what is it? Total Alkalinity (TA) often gets confused with pH and words like alkali, alkaline, etc. I think this topic is one of the least understood in pool management. Many pool service pros know how to test for TA, but may not even know what it actually is, what it does, and why it's important.

How to add calcium chloride to a swimming pool

How should we add calcium chloride to a swimming pool? How can we make sure we're handling it safely, and properly, to avoid unintended consequences? Adding calcium is not as simple as it sounds...you don't just throw it in the pool. Calcium chloride doesn't dissolve the same way as dry acid, sodium bicarb or a non-chlorine shock; calcium chloride gives off a lot of heat. Like any other dry chemical, however, calcium chloride should be pre-dissolved in a bucket prior to adding to the pool. Let's explain.

ORP and LSI: The Future of Water Chemistry

Way back in 1984 I founded my service and repair company, The Pool Surgeon. I had no idea what ORP and LSI abbreviations meant, let alone their definitions. To be completely honest with you, I am not certain I was any better informed in the first 25 years of my pool career. As ashamed as I am to admit it, I'm admitting it because it's the truth.
