Frequently Asked Questions
For rectangular pools, measure length and width. For circular, measure diameter. For oval, measure length and width at the longest and widest points. Depths are measured from the water level to the floor at shallow and deep ends.
Knowing your pool capacity helps in determining the correct amount of chemicals, water treatment, and heating requirements. It's also essential for sizing pumps and filters.
The formula is: Volume (cubic feet) = Length × Width × Average Depth, where Average Depth = (Shallow End Depth + Deep End Depth) / 2. Then convert to gallons (multiply by 7.48052) or liters (multiply by 28.3168).
