Checking spa and pool chemical levels is an essential practice that pool owners overlook. Swimming pool chemical testing is critical because it validates water quality and determines the necessary dosages for correcting the water chemistry. If your water chemistry is left unchecked for long, you might end up with scale-forming or corrosive conditions that can harm your skin.
