Pool Salt Salinity Calculator

As a rough estimate you want to be aiming at around 3,400 ppm (parts per million) for your pools salinity. For every 1,000 ppm increase in salinity level, you need to add 10kg of salt to 10,000 litres of water. For example, if your pool contains 20,000 litres, you need to add 20kg of a 25kg bag of salt.

Note: If using a chlorinator the ppm required will vary slightly depending on the make and design. Low salt concentration below 2000 PPM will render the system ineffective as the salt concentration is too weak. High salt chlorination above 5000 PPM may cause corrosion to pool fixtures.

What is your current salt level: 1000 ppm

How many litres is your pool volume: 20000 litres (5283.44 US Gallons)

Your salt level is between 3300 and 3500 ppm which is a good balance and is correct.
Your pools salt demand: 60 kg

25kg bags of salt required: 2.4 Bags

Your salt is over the recommended limit. You should drain 60 Litres of your pool’s salt water and replace with fresh non-salted water.
