pH vs. Total Alkalinity, and Their Roles in Pool Chemistry - a podcast by Orenda Technologies

pH and total alkalinity are important water chemistry factors that are often confused and misunderstood. This episode explains in detail what each of them are, what they do, and how they interact with other pool chemistry. Since pH impacts just about every other chemistry in water, it is important to manage it properly, according to the physics of water. Too often, pool owners and operators try to control pH, but it is a futile, costly effort.

Show-Notes:
[01:32] What is ph?
[02:30] pH is an equilibrium
[07:58] Negative logarithm of hydrogen
[08:43] Let's not try to control pH. Physics is going to raise the pH in swimming pools.
[09:50] Henry's Law of the Solubility of Gases
[12:23] Buy a ph probe to find out your exact ph.
[12:37] Your ph can raise from algae, vanishing edge pools, spas, spillover, or salt cell.
[17:17] ph is the most impactful factor to the Langelier Saturation Index
[18:53] Problems occur when ph lowers the LSI and water is starving for calcium
[21:16] What is Alkalinity?
[27:38] Adjusting alkalinity
