        Calcium 70  ppm (as CAC0  Calcium Carbonate) x .4 to get calcium ion = 28 ppm
                             3
        Magnesium 10 ppm  (as CAC0  Calcium Carbonate) x .24 to get magnesium ion = 2.4 ppm
                              3
        Alkalinity 60 ppm (as CAC0  Calcium Carbonate) x .61 to get Bicarbonate ion = 36.6 ppm
                             3
        Chloride 16 ppm  as Chloride = 16 ppm
        Sulfate    10 ppm  as Sulfate   = 10 ppm
                        +
                Sodium Na  can only be measure with major equipment such as an atomic
        adsorption or a Mass Spect., however, we can get an educated guess by multiplying the
        chloride ion Cl  x .65 to get an guesstimate of the Sodium. In this case the amount of
                    -
        Sodium would be:
        Chloride: 16 x .65 = Sodium, therefore Sodium = 10.40 ppm















          103.40 ppm


                We just dissected the tap water . . . now add up all the results that are underlined
        and see how close we get to the TDS . The Total comes to 103.40 ppm.

        The approximate TDS is 111.36 ppm
        After adding the ions we got   103.40
        Subtracting those two values

           111.36
        - 103.40
              7.96 ppm

                The difference is 7.96 ppm or mg/l of substances that are not accounted for from
        the TAP WATER . . . THIS IS GREAT!  The water is very well balanced iononicly and the
        remaining difference 7.96 ppm can be attributed to the Sodium as it may be all extra
        Sodium.

          Now lets look at the aquarium tank water from the
                 Wal-Mart in Fayetteville, Arkansas and
              compare this to the tap water starting point.
