    Circupool and my Taylor reading 2 different salinity

    I fired up my swg today, I added 400lbs of salt to my 20k pool, which was supposed to be 2400ppm

    I tested with the Taylor test kit by one drop of the first agent then proceeded to adding one drop at a time until it turns to a red color. Counted 27 drops which is 5400ppm

    However circupool reads 2300-2400ppm which lines up with my salt addition. Did I mess up somewhere?

    Run the pump for 24 hours and brush the bottom of the pool let the salt dissolve before you test levels.

    I added salt since yesterday and it was running all night
    I turned off the breaker for half a day while I was installing the swg. I'll keep the pump running tonight and brush tomorrow and test again tomorrow night.

    It takes 24 to 48 hours for the salt to fully dissolve and mix in the water. Salt readings from SWGs and salt tests can be up to +/- 400 ppm. They are really "ballpark" tests.

    Did you use a 25mL water sample or a 10mL water sample? The K-1766 uses a 10mL water sample (this is a common mistake). If you accidentally used a 25mL sample then the titration is 80ppm/drop.

    If you multiply your 5400ppm by (80/200), then you get 2160ppm which is dead on with what your cell is reporting.

    I used only 10ml of water

    Also, after running for the night then circupool isnreading 3400 ppm average. I'll check again later today
