So today I raised the kh from 5-11 with a powder buffer. I want to maintain it with my fresh auto top of water. Question is should I add the buffer to the container to maintain it or will kalkwasser be a better option?? Obviously I know kalkwasser will maintain calcium also. So which one? Buffer or kalkwasser? My calcium is at 420. Kh is used quickly in my crowded biocube so it always drops to 5.
