Mixing station finally up and running mixing salt as I post. Tested filling from RO/DI to salt container, from salt to salt (mixing), salt out the hose for use in the QT tanks, and salt to the other side of the room to the main sump. RO/DI can go to the RO/DI tank, to the QTs for top off and to the 35 gallon top off for the main.
Makes sense... I'm worried about what evaporation will do to my drywall and am still contemplating if I should install a water/vapor resistant covering over it before I fill my tank. Cuz then it's too danged late lol.
