How to read the chart

Subtract your current salt reading from your target. Example: you read 2,600 ppm and want 3,200 ppm → you need +600 ppm. In a 20,000-gallon pool that's about 100 lb, or 3 bags of 40 lb. For pool sizes between columns, add the columns together (e.g. 25,000 gal = 10,000 + 15,000) or use the pool salt calculator for an exact figure.

Calculated as lb = gallons × 8.34 × ppm ÷ 1,000,000 and kg = litres × ppm ÷ 1,000,000. Bag counts are rounded up (leftovers under 5% of a bag are ignored). Always confirm with a test 24 hours after adding salt and follow your generator manufacturer's recommended range.
