Cloudy water is a hazy, murky appearance that is caused by introduction of suspended particles that are invisible to the naked eye. A similar analogy would be the particles in air that cause smoke. These impurities are introduced to the water from a myriad of environmental sources, even bathers and source water. Particles can intensify and cause water to cloud due to improper water balance, low sanitizer levels and/or lack of routine oxidation, poor filtration or inadequate circulation.
