Cause and effect, I have never heard of anyone using calcium glucomate as a calcium dosing source.

Definately stop dosing the alk and perform a couple larger waterchanges to bring the alk down to 9, and in future use calcium chloride for dosing calcium. If you want to dose a bacteria source use vinegar in really small amounts but generally I've tried to stay away from carbon dosing because it brings some weird strains of bacteria out.
