adding mag based on cal consumption.

test, test, test, i hate em. is it possible to ad mag based on cal consumption?

is the drop linear between the two?

The simple answer.... no not really... Mag is a funny thing and seems to be consumed at different rates in different systems, my home tank for instance uses almost no mag and my water change regime keeps up with demand no problem, but im adding 20 grams per day of cal chloride, then again our open air systems are using quite a bit of mag, and i know someone who says he uses the same amounts of cal and mag, so there is really no way around it without testing..
