Hey organifolk, i was wondering if there's a way to make a calmag supplement for my RO without using nitrates -- using calcium carbonate, magnesium carbonate, magnesium sulfate or gypsum. I know the Epsom salt is soluble but I'm not sure if I'd run into problems w/ the powders. There's no sense in paying 20 dollars for a quart of 6% calmag if I can pay 10 bucks for 5 lbs of something like calcium carbonate. Any advice is appreciated.
