Explanation

Knowing the exact volume of your pool is essential for dosing maintenance chemicals (chlorine, salt, pH) and choosing your filtration pump. ### Formulas - **Rectangular**: Length x Width x Average Depth. - **Round**: Radius x Radius x 3.14 x Average Depth. - **Oval**: Length x Width x 0.89 x Average Depth. ### Average Depth If your pool has a sloping bottom (e.g., 4ft to 6ft), the average depth is (4 + 6) / 2 = 5ft. ### Conversion 1 cubic meter = 1000 Liters = approx 264 Gallons. 1 cubic foot = approx 7.5 Gallons.

Examples

  • Pool 26ft x 13ft, depth 5ft: Approx 12,500 Gallons.
  • Round pool 15ft diameter, depth 4ft: Approx 5,300 Gallons.

FAQ

Why doesn't it match my water bill?

Freeform shapes or steps slightly alter the actual volume.

Which pump for 15,000 Gallons?

You want to turn over the water in about 8 hours. Aim for a pump that moves ~30-35 GPM.
