4.1 Determining Pool Size (Gallons of Water in Your Pool)
• Rectangular Pools

• Circular Pools
Diameter(feet)xdiameter(feet)xaveragedepth(feet)x5.9=galloncapacity.
• Oval Pools

• Sloping Sides

professional.
High Water Temperatures: Because chlorine demand increases with the rise of water temperature, adjustments
must be made in order to keep up with chlorine demand. In hot summer months, where the water temperature
rises above 85ºF, you must increase the pump run time and increase the percentage (%).
