    Adding salt and getting different test results

    Ive added 6 bags of solar salt 40lbs each to 15000 gallon pool. It's been about 24 hours and getting different results each time I've tested. Which test should I rely on?

    Test 1 - digital meter test at pool store said 2400 ppm

    Test 2 - aqua chek strip says 2020 ppm

    Test 3 - swg control board says 2900 ppm (turned unit on and pressed diagnostics button 5x)

    Believe the SWG over anything else, unless it is reading lower than everything else (which can be a sign that the cell is wearing out). Also, keep in mind that all of the tests are +-400 (or worse). In any case, the SWG is the one that needs to be happy about the salt level.

    The salt level never starts at zero. If the pool as just filled it will still be fairly low, but a pool that has been in use for a while often has a salt level over 1000.
