Not much. I have a liter of each and I think it will last me years, easily. It might depend on your water (mine is ph of 7-7.5, ~40 ppm), but just a couple drops does the trick for 5 gallon buckets (-> 5.5 ph).

i dont bother buying ph up or down , just raid your closet and use lemon/lime juice for ph down and baking soda for ph up , there safe to use
