To make this as accurate as possible, It wouldn't be a bad idea to make sure the dry salt mix has been thoroughly mixed before using, to eliminat any possible elemental stratification that may have occurred during shipping.
Make sure you're adding the mix to the RO/DI water, and not the water to the mix. Allow the ASW to mix for at least 4 hours before taking any measurements, to ensure a good mix.
Use a properly calibrated salinity measuring device, i.e. Refractometer calibrated with a 35ppt solution, not RO/DI or distilled water, or a probe calibrated with a 53mS solution. If using another type of device, make a note of it.
What kits were used to measure the Ca, Mg and Alk.
