I've been using Brightwell's Kalk+2 kalkwasser for a little while. I mix about 6 grams per gallon of RO, shake it up, let it settle for a day, and then pour off the clear part (about 80% of the gallon jug) into my ATO. My question is -- what is the white part that is left behind? If some amount of calcium, magnesium and strontium is "dissolved" into the clear liquid, is the white leftover stuff just extra kalk that doesn't dissolve b/c the water is supersaturated? Should I discard the white precipitate or keep mixing with RO until it is gone? Thanks!
