Description
The Pools Scientific Podcast is the only science-based pool care podcast hosted by a credentialed engineer. John Cooper — M.S. Nuclear Engineering, B.S. Chemical Engineering, U.S. Navy Nuclear Operator and submarine veteran, and five-time PHTA certified professional — breaks down pool water chemistry, the Langelier Saturation Index, salt chlorine generators, CYA management, water balance, and everything in between. Built for pool owners who want to understand their water, service professionals who want to sharpen their science, and pool company owners who want a knowledge-based competitive edge. New episode every Tuesday. PoolsScientific.com

Pool plaster mottling gets blamed on your water chemistry almost every time. This episode asks a different question. What if the uneven gray discoloration was decided before the pool ever held a drop of water? We get into the science of new pool plaster problems, and what pool plaster warranty coverage actually protects you from, and what it does not. If your plaster is showing discoloration and mottling in the first few years, you are going to want to hear this one before y...
Pool metal stains rarely come from just one source, and this episode walks through the real chemistry behind them. John covers where metals and minerals actually enter pool water, why iron, manganese, and copper stain differently, and why calcium and magnesium follow the same solubility rules everyone assumes are unique to metals. He breaks down the difference between a sequestrant and a chelator, walks through a rare copper cyanurate case that took fifteen drain and refill cycles...
Closing day is the last time anyone touches your pool's chemistry until spring, and most closing checklists skip the one thing that actually matters: what happens to that water for the next five months. This episode covers pool closing chemistry by pool type, since winterizing an above ground pool, winterizing an inground pool, vinyl liner pool winterizing, fiberglass pool closing, and plaster pool winterizing each carry a different physical risk, not just a different checklist. F...
Why does that sharp chemical smell at the pool mean your chlorine is losing, not winning? This episode breaks down the real chemistry behind combined chlorine and chloramines, the actual mechanism behind the seven and a half percent chlorine-to-cyanuric-acid ratio, and why a fixed LSI range can turn against your pool's plaster and equipment without warning. Includes a real two-year, zero-CYA field experiment on salt pools, and why some of the most repeated advice at the pool store...
Eight real questions this episode, pulled from the Ask John page, the Trouble Free Pool forums, and real clients of the Pools Scientific field lab. Every one of them starts the same way: a reading, a calculator, or a manufacturer spec that looks correct and still leads somewhere wrong. - A plaster pool with a near-perfect LSI still growing scale. - A salt cell manual that flatly contradicts this show's own numbers. - A dosing calculator that's right until, suddenly, it...
