4. Chlorinator OFF, High Salt/Amps (cont.)
The salt concentration will need to reduced. To calculate how much water to drain,
follow the formula provided below (Proportional Method):
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. Then divide that number by the actual salt level in the pool
(based on the independent test).
Part 2: Subtract the “Ave. 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 3200.
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
Step 4E
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.
