Salt Needed (lbs)
Methodology & Sources
To find the salt needed, we calculate the deficit in PPM, convert the pool volume to weight (Gallons * 8.34 lbs/gal), and then apply the PPM ratio/fraction.
The underlying formula used is:
((Target - Current) * Vol / 1,000,000) * 8.34

Frequently Asked Questions
What is ideal salt level?
Most salt generators require 3000-4000 PPM.
How much is 8.34?
8.34 lbs is the weight of 1 gallon of water. We use this to convert volume to weight.
