Locate the current salt concentration at the top of the chart (e.g. 1000ppm). Then locate the size of your pool on the left (e.g. 12,000 gallons). Run these figures down and across until they meet. That number is the number of pounds of salt required for your pool.
CALCULATING THE SIZE OF THE POOL
| Gallons | Liters |
| (dimensions are in feet) | (dimensions are in meters) |
Rectangular | Length x Width x Average Depth x 7.5 | Length x Width x Average Depth x 1000 |
Round | Diameter x Diameter x Average Depth x 5.9 | Diameter x Diameter x Average Depth x 785 |
Oval | Length x Width x Average Depth x 6.7 | Length x Width x Average Depth x 893 |
