Randy, can you maybe explain in which case calcium reactor produce unbalanced Ca/alk? During some period I had big problems, because Co2 dosage was too high. This graph tells a lot:

Left Y axis Ca level from 300 - 600 black marked levels.
Right Y axis kH level from 0 - 18 pink marked levels.
X axis date format dd.mm.yyyy

Last quarter 2004 I used some type of Mg media.

Can you give an example of a change in calcium and alkalinity from one day to another that you think is unbalanced? A period where no water was changed?
