You need to know four different numbers: the length, width,

average depth, and a multiplier that determines gallons. Here is

the formula: Length X Width X Average Depth X Multiplier = Gallons

Determine the Multiplier: Rectangle, square, or free-form

pool:multiplier = 7.5. Round or Oval pool: multiplier = 5.9

Determine the Average Depth: To determine the average depth in a

pool where the bottom slopes, measure the shallow end, the the deep

end depth. Add them together and divide by two (2). Example:

Shallow End = 2'. Deep End = 10' 2' + 10' = 12'; 12'/2 = 6' Average
