Frequently asked questions
How do I calculate my pool's gallons?
Surface area × average depth × 7.48. For a 32×16 ft rectangle sloping 3 to 8 ft, that's 512 sq ft × 5.5 ft × 7.48 ≈ 21,100 gallons. Round pools use π/4 × diameter² for area; ovals use π/4 × length × width.
Why does pool volume matter?
Every chemical dose — salt, chlorine, acid, stabilizer — is proportional to volume. A 20% volume error means every dose you ever add is 20% off.
What average depth should I use?
For a constant slope, (shallow + deep) ÷ 2 is exact. For a hopper-bottom diving pool the true average is a bit less; using the midpoint overestimates slightly, which is a safe direction for salt.
