4 Steps to Fix Your Pool After Heavy Rain
Test pH and total alkalinity first Rainwater is acidic (pH around 5-6) and dilutes your pool chemistry. Get pH back to 7.4-7.6 and alkalinity to 80-120 ppm before doing anything else.
Shock the pool Heavy rain brings in airborne dirt, pollen, and runoff. A shock treatment kills contaminants and stabilizes chlorine levels.
Run the pump for at least 8 hours Circulation is critical after shocking. Keep the pump running to filter out debris and distribute chemicals evenly.
Drain excess water if needed If you got a foot of rain, lower the water level so the skimmer works properly. Your pool should be swimmable by the next afternoon.
