Salt Calculator
How to calculate the optimal salt level for your salt chlorinator pool?
A pool salt chlorinator’s proper functioning relies directly on respecting the recommended salt levels in the water. An optimal salt level maximizes natural chlorine generation, guarantees efficient sanitization, and protects the performance of your automatic water treatment system.
Unfamiliar with the technology? Please refer to your chlorinator's user manual. The vast majority of devices operate in Normal Salt mode.
Measured using a test strip or an electronic tester. For a first pool filling, leave the value at 0.
Conversions and Calculations
-
Volume: 1 m³ = 1,000 L of water
-
Salt level: 1 g/L = 1 Kg/m³
-
Amount of salt (kg) = Water volume (m³) X salt level (kg/m³)
Steps to determine the ideal salt level
1. Check your chlorinator’s recommendations
Each salt chlorinator has its own specifications. Refer to the user manual of your Pool Technologie device to find the recommended salinity range to ensure optimal sanitizer production.
4. Adjust the salt level if necessary
If the measured concentration is below the recommended value, add special pool salt. Conversely, if the level is too high, a partial water dilution may be necessary. Use the salt calculator to find your pool’s requirements in just a few clicks.
2. Measure the current water salinity
Use a salt tester or a conductivity meter specifically designed for pools treated by salt electrolysis. The result is generally expressed in grams per liter (g/L) or in parts per million (ppm).
5. Allow the salt to dissolve completely
After adding the salt, keep the filtration running for at least 24 hours to achieve homogeneous dissolution and a reliable salinity measurement. Ensure that the salt does not clump at the bottom; use a pool cleaner or brush the bottom to make sure the salt is caught in the water flow.
3. Verify the recommended operating range
Depending on the pool chlorinator model, the optimal salt level is generally between 2.5 and 5 kg/m³ (2,500 to 5,000 ppm) in Normal Salt mode. This concentration allows for efficient chlorine production while ensuring swimmer comfort. For low salinity devices (Low Salt), the optimal salt level ranges between 1.5 and 2.5 kg/m³.
6. Check the salt level again
Once the mixing is complete, take a new measurement to verify that your salt pool falls within the range recommended by your water electrolysis system.
Why maintain an optimal salt level?
A correctly adjusted salt level allows you to:
-
Improve the efficiency of your pool chlorinator;
-
Ensure a steady production of natural chlorine;
-
Guarantee flawless water quality;
-
Limit premature wear on the electrolysis cell;
-
Optimize the performance of your Pool Technologie automatic treatment system.
For optimal operation of your installation, it is recommended to regularly check the water salinity and the balance parameters (pH, Total Alkalinity [TA], and stabilizer).
