u gotta see how much ur tank takes up a day in calcium... but in relationship to calcium you got alkalinity which also needs to be measured.. and dont forget magnesium which makes both calcium and alkalinity stay in balance ...
everyday your tank uses up all 3, from reading and my daily observation our tanks take up alot more alkalinity then calcium and magnesium...
so to answer your question no do not stop dosing but find out how much you need to dose on a daily basis in ml....
