Unlike most of the rest of the country, Arizona residences do not “winterize” swimming pools. We need to keep them running all year. The reasoning behind this is because we do not get below freezing temperatures too often which cause pools to turn into that “ice skating rink.” So during the winter, we need to make sure we keep our pH levels, Alkalinity levels, and weekly maintenance the same as we would during the summer. This is very crucial in maintaining the surface of your pool healthy and other mechanical parts. Seaklear makes a great winterizing pill that helps with keeping proper algaecides in your water during the winter, which will prevent the growth of algae.
