Biologists estimate that water makes up 65% of the human body, 71% of the planet's surface, and 0% of the R & B group Earth, Wind & Fire. Maintain the planet’s most prevalent liquid with today’s Groupon to OZ Property Services. Choose between the following options:

• For $60, you get one month of weekly pool services (a $125 value).
• For $170, you get three months of weekly pool services (a $375 value).

The pool tenders at OZ Property Services administer a host of weekly services to ensure aquatic environs glisten with pristine waters. During each one-hour weekly visit, technicians test the chemical balance of chlorine, pH, alkalinity, and stabilizer before skimming the crystalline surfaces for debris and waterlogged polo mallets. A thorough tile and wall brushing removes stubborn deposits of algae, and a vacuuming eliminates sunken refuse and leviathan eggs. Clients wishing to extend their services for a month beyond the length of this Groupon may do so at a special rate of $65.
