Kalkwaser

[Metrontech]

Need some help. I have been looking into using kalkwasser with my gravity fed ato.

I have a 120 display with 55 sump. So probably 140 with displacement. Give or take.

I have tried doing calc and mag but just can't get it to stay stable.

I have read thst kalkwasser is a simple way to keep things stable.

But have also read that it can't keep up with the calcium demands on some tanks.

Amy input or tips?

I would prefer to hear from those who are using kalkwasser in the ato.

Thanks in advance

Mike
