This topic is fascinating to us. It is also an incredibly helpful lesson that explains why pH naturally rises. If you maintain pools on a weekly basis, you probably notice the pH is almost always higher when you come back after a week. That's not your fault. It's natural. This article explains why.
ideal pH for pool
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.
Pool industry textbooks and certification courses tell us that swimming pools should be maintained ideally between 7.4 to 7.6 pH. But why? Is it for sanitizer efficiency or overall water balance? Or perhaps it is because of swimmer comfort. Everyone we have asked in the pool industry makes mention of the pH of human tears...but a simple online search debunks that myth. So let's challenge conventional wisdom and get to the truth.
It happens all the time. Swimming pool pH climbs, or sometimes spikes, and all sorts of problems like calcium dust and carbonate scale can occur. But what causes high pH in pools? Why does the pH sometimes climb, and other times stay relatively steady? In this article, we will discuss pH and how it shifts, and offer some remedies to correct the pH, based on each situation.
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.
