A pool chiller will take anywhere from 12 to 14 hours to lower your pool's temperature by 1 to 15 degrees. Most people tend to run their coolers overnight, but larger pools in warm climates take longer to cool. Choosing a chiller with the right capacity can help speed up the process.

Chronic chlorine exposure (meaning multiple or repeated instances) can make you feel like you have the flu, according to the CDC.

A well-built and well-maintained concrete pool should last anywhere from 50 to 75 years. Concrete is prone to cracking, so winterization and regular pool repairs are particularly important. Water can seep into existing cracks, freeze, and make them worse. Most homeowners should resurface their concrete every few years to maintain their pool’s lifespan.
