input on kalkwasser

[monza]

I don't know anything about just using Kalk as a a calcium and Alk suppliment in your top of water alone, can't see that working.

Why can't you get your dosing to balance? I'm assuming by balance you mean a steady level of calcium and Alk at your desired level. It's pretty easy you simply add more or less while testing calcium and Alk, mostly alk.
