Bob Lowry: The Truth About Persistent High pH in Pools

Your pool pH isn’t “random” or “stubborn” and once you understand what’s actually driving the rise, you can finally stop the endless acid cycle. We dig into the real reason pH climbs week after week: CO2 off gassing. Total alkalinity controls how much carbon dioxide wants to escape, and when alkalinity is too high, the water is essentially overcarbonated. As CO2 leaves the water to reach equilibrium with the air, pH rises, and the problem repeats. We also get honest about the pools that figh...
