More Rookie Pool Chemistry Mistakes Pt.2 – Bob Lowry

Think a four-hour pump schedule is “good enough”? We put that myth to rest with clear math, real-world examples, and a simple plan for dialing in filtration so you stop chasing cloudy water and recurring algae. With Bob Lowry in the chair, we unpack why three turnovers is the sweet spot for clarity and safety, how to measure true flow instead of guessing, and what happens to sanitizer when circulation goes quiet for twenty hours a day.We also get honest about bather load. A backyard pool can hit zero free chlorine minutes after seven adults or a pack of energetic kids jump in. That’s not scare talk—it’s demand math. We walk through why “keep chlorine low” backfires in stabilized pools, how cyanuric acid changes your targets, and the exact pre-party and post-party steps to protect swimmers and keep callbacks off your weekend. You’ll hear practical guidance on variable-speed settings, placing a flow meter, and setting run times around gallons per minute, not habit.Training ties it all together. Quick seminars often isolate one idea—like higher CYA—without showing the trade-offs for pH control and chlorine strength. We share why full-scope chemistry education builds confidence, speeds decisions on route, and helps you explain choices to cost-sensitive homeowners with data they can trust. You’ll learn where to find live and online pool chemistry certification, how to access technical bulletins, and how to turn testing-first into a repeatable, profitable workflow.• three turnovers as the target for clarity and safety• how to calculate turnover using actual flow rate• circulation’s role in stopping biofilm and algae• bather load math that crashes free chlorine• why “keep chlorine low” is bad advice with CYA• simple pre-party and post-party dosing plans• full-course training versus one-hour seminars• where to find certifications and tech bulletins• daily workflow: test first, then dose with purposeJoin the pool guy coaching program.
