Bob Lowry’s Start-Up Science for Every Pool Surface

Fresh plaster only gets one chance to cure right, and most problems start before the first cannonball. We dive straight into the real-world startup decisions that determine whether your pool finishes smooth and stain‑free or inherits permanent issues. With veteran insights from chemical expert Bob Lowry, we compare the big methods—barrel, traditional, and acid—and map clear rules of thumb for when each one makes sense based on source water and surface type.We get practical fast: test the fill water before you open the hose, set calcium to at least 150 ppm on day one, and decide how to handle metals the smart way. You’ll hear why hose‑end pre‑filters beat sequestering agents, how to use skimmer removal media effectively, and why sequestering alone fails as it breaks down under sunlight and chlorine. We also unpack the plaster dust problem, showing how a slightly low pH keeps dust soluble without risking surface burn, and why cartridges outperform sand when you need to capture fines.New plaster is fragile, so we outline the non‑negotiables: never stop the initial fill, protect the surface from hose damage, keep wheels and robots off for weeks, and keep pets and people out until balance stabilizes. Whether you’re a service pro scaling up or a homeowner protecting a six‑figure investment, this guide gives you the steps, targets, and tools to start clean and stay clean. If this helped you sharpen your startup playbook, follow the show, share it with a colleague, and leave a quick review so more pool owners and pros can find it.• why startups shape the life of the surface• barrel vs traditional vs acid methods and where each fits• testing fill water for calcium, alkalinity, copper and iron• hitting 150 ppm calcium on day one for balance• removing metals with pre‑filters and skimmer media• limits of sequestering agents and why they degrade• managing plaster dust with controlled pH and filtration• new plaster cautions: continuous fill, no wheels, no pets• recovery steps when builders skip startup• record‑keeping with printed guides and mobile appsSend us Fan MailSupport the Pool Guy Podcast Show Sponsors! HASA https://bit.ly/HASAThe Bottom Feeder.
