    R/O Remineralizer

    Hi

    I would like to make a DIY remineralizer/alternative to Kent RO Right etc. for R/O water and I was wondering if anybody knows where I could get a hold of these in Canada
    (I know some of them can be purchased from local hydroponics shops but having a hard time finding the rest):

    K2SO4
    CaSO4
    MgSO4
    FeSO4
    MnSO4

    PS: I'm in Edmonton, Alberta

    I doubt you will find most locally unless you luck out with a local chemical supply house, instead check Ebay or Amazon, also consider common names...

    CaSO4 = powdered gypsum (lots of options like just harvesting it out of a sheet of drywall or plaster of Paris, but purity is questionable in both of those, so I would avoid)
    MgSO4 = epsom salt (probably the easiest to find at just about any pharmacy even Walmart, just make sure it's pure pharmaceutical USP grade)
    FeSO4 = green vitriol
