Algae pressure, drifting pH, and vanishing chlorine can make pool care feel like a tug of war. We sat down with renowned chemist and educator Bob Lowry to map out a cleaner, calmer path: use borates the right way, match your CYA to your chlorine needs, and stop fighting the water. The conversation cuts through marketing myths to show why boric acid at 50 ppm stabilizes pH and supports sanitizer performance without turning your maintenance plan upside down.We start by reframing borates as a tool, not a cure-all. Bob explains the simple pairing that drives clarity: free chlorine maintained at about 5 percent of CYA with a minimum of 2 ppm. For most outdoor pools, that points to 40–50 ppm CYA; for salt water chlorine generators, 70 ppm often works better because it protects fresh chlorine produced at the cell and near the sunlit surface. Expect steadier weeks with fewer spikes, not a set-and-forget miracle.Product choice matters. Boric acid barely changes pH or alkalinity, while borax-based products can push pH near 9 and add roughly 115 ppm to total alkalinity, demanding large acid corrections and risking scale if calcium is high. Bob details how pre-balancing and LSI awareness prevent cloudy water, plus practical dosing math and the limited but workable testing options. Field experience and historical research converge on 50 ppm as the effective algaestat level, with 70 ppm a smart ceiling for SWGs seeking extra stability and clarity.If you want water that holds its balance, sparkles in the sun, and uses chlorine more efficiently, this guide lays out the steps: choose boric acid, set CYA with intent, maintain a real chlorine residual, and top off borates only when water leaves the pool. • borates as a pH buffer and algaestat at 50 ppm• chlorine set at 5% of CYA with a 2 ppm floor• CYA targets of 40–50 ppm and 70 ppm for SWGs• boric acid vs borax forms and acid demand• LSI risks when TA, CH and pH run high• dosing math and maintenance dosing over seasons• limited testing options and practical workarounds•Send us a textSupport the Pool Guy Podcast Show Sponsors! HASA https://bit.ly/HASAThe Bottom Feeder.
