In order to figure out the proper doses of chemicals for your pool, you need to determine how plenty of gallons that water it holds. To do that, you must use a leader to measure your pool to uncover out these four different numbers; Length, Width, mean depth and also a multiplier that determines gallons.

So below are the formulas to number out exactly how much water is in your swimming pool:These formulas organize true for both Inground pools too as over ground pools.

Rectangular, Square or Free kind Pools:

Length x broad x typical Depth x 7.5 = complete gallons

For example: 16′ x 32′ x 4.5′ x 7.5 = 17,280 Gallons

Circular Pools:

Diameter x Diameter x average Depth x 5.9 = full gallons

For example: 18′ x 18′ x 4′ x 5.9 = 7,646 Gallons

Oval Pools:

Length x broad x mean Depth x 5.9 = full gallons

For example: 15′ x 30′ x 4′ x 5.9 = 10,620 Gallons

How to determine the median Depth of a swimming Pool whereby the bottom slopes:

Below is a side-shot the the “typical” inground pool that has a shallow finish (see “D”), climate a slope that leads into the deep finish (see “C”).

First measure up the depth the “D”, the shallow end (usually all over from 3′ to 5′), and also then measure up the depth the “C”, the deep finish (usually anywhere between 6′ and 12′) . Then, add them together and also divide by 2. This is the average depth of her pool.

For example, if her shallow end “D” is 3′, and your deep finish “C” is 8′, this would certainly be her formula because that the typical Depth:

3′ + 8′ = 11′

11′ separated by 2 = 5.5.

Therefore, in this example, your mean depth would certainly be 5 1/2 feet.
