While waiting for TA, pH, and chlorine levels to drop to treatable levels for phosphates and rust stains, our desert weather changed, dropping water temps to below 65ºƒ, probably 'til Spring 2021 or so. Winterizing a pool here means keeping the pump running during the occasional freeze warnings. Otherwise, pool remains uncovered, the pump runs four hours a day, monthly chemical checks, and monthly brushings. Thanks...JS
