Saltwater Parameters

The following parameters can be tested in salty water


Parameter Fresh water Saltwater Seawater
Active oxygen  
Chlorine dioxide  
Cyanuric acid  
Total hardness    
Calcium hardness  
pH  *  
Hydrogen peroxide


* Special case pH measurement

Depending on the salt content of your sample, the measurement result must be corrected according to the following scheme:

1 molar = -0,21 pH
2 molar = -0,26 pH
3 molar = -0,29 pH
where: 1 mol salt (NaCl) = 5.8 % = 58.4 g/l

Pools with salt electrolysis are not affected.
In salt electrolysis, a maximum of 7 g/l salt is used, far less than 1 mol (58.4 g).
