    Salt test strips vs. SWG reading

    Are salt test strips really worth it when my Hayward SwimPure/AquaRite is taking a measurement of the salt content for me? Does anyone know how much more accurate? Does the AquaRite seem to read higher or lower?

    Re: Salt test strips vs. SWG reading

    It depends. It is always good to have an independant test. One sign of a failing cell is if the SWG starts reading a salt level well below the actual salt level.

    I think the drop based K-1766 kit is more accurate than the strips.

    FYI, I installed a new SWG yesterday and it is reporting salt at 2600ppm while I am testing 3200ppm (and a pool store got the same thing). So, it seems that mine is reading a little low ... hopefully this difference is within the accuracy to the 2 testing methods and there is not a problem. I am likely to just add a few more bags of salt to make the SWG happy.

    The better salt tests and most SWG salt meters are +-400.
