Often times premixed from lfs. Is mixed to the bare minimum 1.o22 to 1.o23. Less salt per gallon sold. Equals 10 to 20 % more profit over 1.026. And ph runs lower when mixed at minimums. In the long run an rodi and mixing your owne will save you a little bit over a years time and offer better parameters. All while providing better accessibility to much needed water for emergencies
pH is not really directly related to salinity. It is determined by alkalinity and CO2 in the water which is usually driven largely by the CO2 level in your home air.
