And you would naturally need to add some NaCl-free supplemental salt (I use Tropic Marin Pro-Special Mineral) in the right amount. You can also add MgCl2(6H20) and MgSO4(7H2O) in the right amounts to keep the Mg-level constant. Requires some calculating to get the right balance.
I guess a...
Could there be any problems using theese both methods at the same time? I see a great advantage in using the kalkwasser, but I still need to add more Ca to maintain reasonable values.
Not. The Balling method uses CaCl2, NaHCO3 and NaCl-free seasalt (to correct the ionic-balance).
