based on standard 20kg bags
Salt required
52.5 kg
That is approximately 2.6 bags of 20kg salt.
Required increase: 1,500 ppm
How it works
The calculator estimates the kilograms of salt needed from the difference between your current and desired ppm, based on your pool volume.
Best practice
Add salt gradually, brush where needed, and circulate the water well before re-testing. Always confirm the ideal range for your chlorinator.
