I just opened my pool and am having trouble with the salt readings.
Test strips (a couple of years old) show the salt level at 3540, which is surprising since that's about where I thought I left it last year before closing.
The reading on the Aquapure SWG shows 2400.
The pool temperature is only about 64 degrees, but there is nothing in the Aquapure documentation that shows that would affect the salt calculation.
Which number should I believe? Could the higher reading be the result of old and faulty test strips?
