I cannot prove the absence of anything! I can only prove the presence of
what I analytically read with my instruments.
It's not K2CO3 at 100%, and I'm pretty sure that there are no any other
carbonates but there is Ca and Mg. I don't know which are the negative ions
associated because I didn't make any test on those, even if I suppose that
there should be CaSO4 and MgSO4 cuz in my tank the level of SO4-- ions is
pretty high and I've never add any.
And some chelator specific for clorine should be present as well.
