Pool pH Made Simple: Raise It, Lower It, Lock It In

Fighting red eyes, cloudy water, or scale that keeps coming back? We unpack the exact chemistry that drives pool comfort and clarity, then give you a simple plan to control pH without wrecking alkalinity. You’ll learn why total alkalinity is the true pH buffer, how cyanuric acid and borates play supporting roles, and when to pick borax, baking soda, or muriatic acid to get fast, stable results.We start with the essentials: what pH means for swimmer comfort, equipment protection, and chlorine strength. From there, we explain how high alkalinity blunts acid and traps you with rising pH, while low alkalinity removes the cushion and lets pH crash. We walk through smart targets for plaster, vinyl, and fiberglass pools, and show how trichlor tablets quietly push pH and TA in the background. If your salt pool drifts high, you’ll hear why turbulence from the cell accelerates pH rise and how borates at 50 ppm calm the swings while boosting chlorine performance.Then we get practical. Skip the mess of soda ash and use 20 Mule Team Borax to raise pH cleanly with minimal impact on TA. Use baking soda only to raise alkalinity. When TA is sky-high, follow our proven cycle: create aeration with a submersible pump or water features, dose measured acid to lower TA, let turbulence lift pH back up without changing TA, and repeat until you’re in range. We also share dosing tips, why borates mean you’ll need a bit more acid, and how to set up a stable “buffer stack” that keeps water clear and comfortable.• ideal pH targets for comfort and sanitizer strength• corrosion risks at low pH and scaling at high pH• alkalinity as the main pH buffer and target ranges• cyanuric acid’s minor buffering and tablet effects• borates at 50 ppm for pH stability in salt pools• why muriatic acid lowers both pH and alkalinity• why soda ash clouds water and spikes alkalinity• borax as a cleaner way to raise pH• baking soda for raising alkalinity only• step-by-step aeration method to lower high alkalinity• practical dosing notes and app recommendationSend us Fan MailSupport the Pool Guy Podcast Show Sponsors! HASA https://bit.ly/HASAThe Bottom Feeder.
