mixing kalk
 

does anyone add vinegar to theirs?

I add 1 tsp to 2L, it's common practice. That link suggest 1tbsp though.

I never had the need to add the vinegar.

I use to add 2ml to a gallon jug of top off with 2 tablespoons of kalk, found it helped some what in disolving the white stuff!
Now I no longer use kalk and instead it's Liquid Reactor for me :biggrin:

I have been adding 3tbsp to 6L of water

I don't use vinegar. Regular strength Kalk is more than enough for my needs at the moment.
