To calculate how much water will need to be removed from a pool, with too much

salt, follow the formula provided below (Proportional Method):

Salt Dilution Formula

Part I

(Ave. Pool Depth” X 3200)

Actual Salt level in Pool

Part 1: Take the average depth of the pool in inches and multiply that by

3200 (or desired salt level within 1500-4500ppm). Then divide that

number by the actual salt level in the pool (based on independent test).

Part 2: Subtract the Average Pool Depth by the answer from part 1. This

will give you the total number of inches to drain and replenish with fresh

water to achieve a salt level of to match desired salt level from step 1.

Part II

Ave. Pool Depth - Answer from Part 1 = Amount of Water to Drain

Example: a pool has an ave. depth of 54” and the salt level is 4500ppm

54 X 3200 = 172800

4500

38.4

Example: Part I

54 – 38.4 = 15.6”

Example: Part II

Note: It is recommended to reduce the water level no more than six inches at a time before

replenishing with fresh water. Failure to due so may result in damage to the pool structure or

surface.
