Re: GH. kh and ph

bicarb is sodium "Na" and bi-carbonate "HCO3"
the second half of the equation "HCO3" is what buffers your pH and nothing else really in terms of what your are measuring
the "Na" does not add to the GH its not part of what your reading but it will add to the TDS
i presume your GH is 14 gdh and not .14 as you put it so
yes you add bicarb untill your KH is higher than the GH then add nothing but ro water then they should fall equally
what you had originally i suspect is what many people including me have is out of the tap a KH of around 4-5 GDH and a GH of 15-20GDH and of course when you run the KH out totally of say a GH of 20, you will still have a GH left of 15 gdh
hope this makes sense ?

so add more KH while you run the gh down, you do this several times keep taking the kh up to 5gdh every time then running this out i dont recommed doing it in one hit that was just for demonstration and example purpose

Re: GH. kh and ph
Ok Duncan, i think i understand, i add bicarb daily till its higher than the gh as i top up with just RO water.?
MY tap gh is 18 and kh around12.
