Understanding Total Dissolved Solids (TDS)

Total Dissolved Solids (TDS) is a metric used in water treatment that measures all dissolved minerals, salts, chlorides, metals, organics, and many other contaminants in water. TDS impacts water conductivity and is related to corrosion, chemical efficiency, water clarity, and is an often-forgotten factor in the LSI.

Does Temperature Impact Cyanuric Acid Performance?

Today we are discussing two of the six LSI factors: water temperature and cyanuric acid (CYA). Specifically, does warmer temperature affect CYA's ability to protect sunlight? There is a widespread belief in the industry that hotter weather means you need higher CYA to protect chlorine from sunlight. So we asked a leading expert about what's really going on.

Chlorine, pH and Cyanuric Acid Relationships

We have always been taught that pH controls the strength of chlorine. And that's true, except when cyanuric acid is in the water too. CYA changes the entire dynamic. Fair warning, this topic is controversial and contrarian to most textbooks and industry beliefs. But it is backed in science that we will cite in this article. Buckle up.

Weepers, Efflorescence, and other Concrete Pool Shell Problems

Believe it or not, swimming pools can leak in both directions. Most of us think of pool leaks as water escaping out of the pool, but this article is about water pushing into the pool from the outside from hydrostatic pressure. We'll discuss what the consequences are, how to fix them, and more importantly, how to prevent these issues from the beginning.

Evaporation and Accumulation

When water evaporates, it leaves behind minerals, metals, and other dissolved solids like salt. Naturally, whatever is left behind will accumulate over time. Let's discuss the impact that evaporation has on water chemistry, and how you can be proactive and adapt to it.

How to Add Acid to a Swimming Pool

Do you need to reduce alkalinity or pH in a swimming pool? If so, you may need to add some acid. This article introduces the best known practices for how to safely handle acid products, and how to add acid to a pool properly. Yes, it DOES matter how (and where) the acid is poured in the pool. And we debunk the myth of the "column pour."

Scale-Forming Tap Water

We recently had to adapt the Orenda Startup for a unique tap water situation.

Most tap water we test is low on the Langelier Saturation Index (LSI). On the Orenda app, it shows up with a red LSI number at the bottom. And by "most tap water", we mean almost all tap water in the country. That is, until the water we tested recently in the Bay Area of Northern California. It had a purple LSI.
