Green to Clean

The primary reason a pool turns green is when algae begin to bloom. Here in Phoenix, a monsoon dust storm can turn a bright clear swimming pool to a murky green swamp in just 24 hours. Leaves, dust, and other debris quickly tax the chemical balance of the pool water and allow algae to take advantage. Pools and spas in vacation homes and bank-owned properties are especially susceptible to turning green and staying that way for far too long.

Neglected and infrequently used pools that turn green become breeding grounds for disease-carrying mosquitoes, bacteria, fungi, and other microorganisms. The dark water hides debris which can be very hazardous for animals and people who may fall in. Green pools present a health hazard to the entire community. Maricopa County is continually trying to control mosquitoes carrying West Nile Virus. The county chemically fogs large areas to combat pests. Additionally, they are cracking down by prosecuting violations and assessing fines.
