15-Foot Round Pool Capacity Guidelines
• Total Water Volume: 5,310 Gallons (48-inch wall) or 4,440 Gallons (42-inch fill)
• Salt Needed: 142 lbs (3.5 to 4 bags of 40 lb pool salt)
• Filter turnover: Needs minimum 1,000 GPH pump flow rate to turn water twice daily.
Water Weight and Ground Leveling Importance
At 5,310 gallons, water weight exceeds 44,000 lbs (22 tons). Ensure your ground is 100% level within 1 inch to prevent frame collapse or liner rupture under this load.
