Kalkwasser ?

[mitch303]

I am wanting to start dripping kalk. I have tried to mix it a couple times but I have not been doing out right or something because I never get the layer on the bottom. I am using a 1 gallon millk jug how much am I supposed to mix it?

[funkejj]

two table spoons per gallon.

Adding a little vinegar in there can help as well.
