in order for a CaCO3/CO2 reactor to dissolve Mg the pH would have to be considerably lower then we run (to the point it would mud the media pretty quickly) therefore any Mg that's in your media is coming out as a precipitant and does little for helping keep the tanks levels up. back yrs ago we all used to add a few handfuls of Dolomite to the reactor but it never did any good.
the 3-5 ratio is balanced, i don't see why it would then be unbalanced just because you use a CaCO3/CO2 reactor or Kalk, if that were true, then using the reactor or Kalk without a Mg supplement would also be throwing your system out of ionic balance, i think most would agree that's not happening.

it's my understanding that one ionic imbalance is just as bad as the other. with that said if you have to use just a single additive the imbalance is lesser by the use of MgCl then the use of MgSO4 for the same ppm increase for a given volume of water.
