Improved 2 part recipe and lime water


New member
My Alk/Ca needs are becoming more then what my limewater can mantain so I'm considering to use the "improved two part alk/ca recipe" to make up the difference.

Is it ok to continue using limewater as a evaporation replacement if I start using the homemade recipe or should I stop using limewater and only use R.O. water to replace evaporation?

I can't speak nation/world wide but in our local club it is pretty common to use both Kalk and 2 part methods on the same tank since CO2 levels can be high in the home during wintertime the PH boost of Kalk is quite beneficial.
