  "description": "15x30 oval is a common above-ground pool footprint that fits more swimmers than a round pool in a similar yard space. This calculator uses the ellipse area formula with a default 4-foot depth to return total gallons for chemical dosing and pump sizing.",
  "formula": "Gallons = π × (Length ÷ 2) × (Width ÷ 2) × Average Depth × 7.48.",

      "a": "At a 4-foot average depth, about 10,573 gallons, notably more than a comparable round pool due to the larger surface area."

    {
      "q": "Is the oval area formula the same as a circle?",
      "a": "No, an oval (ellipse) uses half of each dimension as the two radii, so the formula multiplies both half-length and half-width by pi rather than squaring one radius."
    },
    {
      "q": "Do oval pools need a bigger pump than round pools?",
      "a": "Generally yes, since they hold more water — size the pump and filter to turn over the full gallon volume within about 8 hours for adequate circulation."
