This is not a descaler you run after the scale has formed — it is a conditioner you add at every refill so the scale has a harder time forming in the first place. Two drops per gallon.
The citric-citrate system sequesters calcium and magnesium ions while they are still dissolved, before they can precipitate onto tank walls or blow out as white dust. Three food-grade ingredients and nothing else: no silver, no copper, no metals of any kind, no surfactants, no fragrance, no dye. One 2 fl oz bottle covers over 550 refills.
