I go through periods where I pay close attention to the chemistry in my reefs and other periods where I test and adjust alk, Ca and Mg rather infrequently. When dripping kalk nightly, I really notice how low Mg gets and how Ca stays at about 400 ppm. When I don't drip kalk for periods of time, Ca and Mg get low. Alk is always low, whether I drip kalk or not, though it is much, much lower when I don't drip kalk nightly.
I wish the chemistry guy at RC would do a study on how much Mg and how much Ca is required to build stony corals, coralline algae and calciferous algae. We might be surprised with what he finds out.
