Salt chart: pounds by pool size and ppm increase
Pounds of salt to raise salinity by a given amount, from lb = gallons × Δppm × 8.34 × 10⁻⁶. Use the salt calculator for your exact current and target ppm.
| Pool (gal) | +500 ppm | +1,000 ppm | +1,500 ppm | +3,200 ppm |
|---|---|---|---|---|
| 10,000 | 41.7 lb | 83.4 lb | 125.1 lb | 266.9 lb |
| 15,000 | 62.6 lb | 125.1 lb | 187.7 lb | 400.3 lb |
| 20,000 | 83.4 lb | 166.8 lb | 250.2 lb | 533.8 lb |
| 25,000 | 104.3 lb | 208.5 lb | 312.8 lb | 667.2 lb |
| 30,000 | 125.1 lb | 250.2 lb | 375.3 lb | 800.6 lb |
To reach a common salt-pool target of 3,200 ppm from zero, use the +3,200 column.
