Understanding salt levels in your pool despite a water change.

Client :
Hello, my Aquarite is indicating a salt level of 4.2 even though the pool was half emptied of its water. Do you have an explanation? THANK YOU

Technical Advisor :
Hello

Technical Advisor :
Salt level, do you mean pH?

Client :
No, pool salt level.

Technical Advisor :
Okay, no. But it's a concentration, so emptying the pool should not have any influence.

Client :
It was refilled.

Technical Advisor :
The pool level is not at that measurement.

Client :
No, it's lower, about 2.2.

Technical Advisor :
What's your pH? What's your redox value?

Client :
7.3

Technical Advisor :
And the redox (mV)?

Client :
730, I think.

Technical Advisor :
That seems correct! You're welcome, feel free to contact us again! Have a great day.
