FAQ
Why are there different factors? +
7.5 gallons per cubic foot is the conversion. Round and oval pools use a smaller factor because their actual surface area is less than the bounding box.
My pool has different depths +
Use the average depth (shallow end + deep end ÷ 2). Close enough for chemistry and fill estimates.
