Do you still do manual dosing like a three part? Well i guess you still need mag does it keep it 100% stable or you you still need to polish off your dosing manualy?
If the kalk can't keep up with the calcium, you can always supplement with two part. I had to do that when I was raising my Mag and Calcium, but once I got it to the level I wanted, I haven't had to dose liquid calcium again.
