How much water do you need?

In order to know how much water you'll need to fill your pool (and figure out proper doses of chemicals), you need to figure out how many gallons it holds. To do this, you need to know four numbers: Length, Width, Average Depth, and Multiplier based on your pool type.

 

 Pool Volume Formula

Length x Width x Average Depth x Multiplier = Volume in Gallons

​

 Determine the Multiplier

Rectangle, Square and Free Form Pools: Multiplier = 7.5

Round and Oval Pools: Multiplier = 5.9

 

Determine the Average Depth

To determine the average depth in a pool where the bottom slopes, measure the shallow end, the deep end depth. Add them together and divide by two.

​

Example:  Shallow End = 2ft. Deep End = 10ft
2ft + 10ft = 12ft; 12/2 = 6ft Average Depth
