A saltwater pool is a chlorine pool: a salt cell makes the chlorine. Cell electricity and wear per gallon of liquid chlorine replaced, upkeep and corrosion from the manuals, and the stabilizer tablets add in 19 US cities.
One label shock dose adds about 5–10 ppm free chlorine. Label doses for liquid chlorine, cal-hypo, dichlor and non-chlorine shock, SLAM levels by stabilizer, and the CYA that weekly dichlor adds by city.
Free chlorine 2–3 ppm, pH 7.4–7.6, alkalinity 80–120 ppm, calcium 200–400 ppm, stabilizer 30–50 ppm: every range tied to CDC or a manufacturer’s manual.
