Care / Knowing your Pool

Pool Shapes and Sizes

Before you begin treating your pool, it is essential to know how much water your pool holds. It is not uncommon for pool owners to underestimate the amount of water in a pool, continuously underdose, and then wonder why they have problems.

Rectangular or Square Pools

Multiply length (metres) x width (metres) x average depth (meters) x 1000 = size in litres

Circular Pools

Multiply the diametre (meters) x diametre (metres) x depth (metres) x 0.79 x 1000 = size in litres

Oval pools

Multiply the long diametre (metres) x short diametre (metres) x depth (metres) x 0.79 x 1000 = size in litres

Kidney and other unusual shaped pools

Unusual pools can often be broken down in to basic shapes for purposes of calculation. For example, a kidney shaped pool is roughly two circles joined together. Calculate the volume of the circles and add on about 10% to cover the area not included in the calculation. It is better to overestimate a pool volume than underestimate it.

Note: Average depth is calculated by measuring depth at the deep end and at the shallow end, adding the figures together and dividing by two.
