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.
high pH in pool
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.
