Forgive me for sounding stupid, but the only silly questions are the unasked ones right? So...... Say you're dosing all for reef and let's say for argument's sake, with a constant maintained dosage your alk sits at 8dkh, magnesium at 1400 and calcium at 400 and all is stable. Then you start to dose kalkwasser in addition to the afr at a rate which sits right with your evaporation etc.
I would assume your alk and calcium would begin to rise (as well as pH) so let's say after a given time your alk then rises to 9 dkh and calcium rises to 450 but your magnesium would stay the same (or possibly drop due to imbalance?)
Then in theory, kept at the same rate your cal and alk will continue to keep rising to undesirable levels? Or am I missing something?
