I have heard talk of a product that allows you to mix kalk powder directly to one gallon of ro water and add directly to your tank for water top off. 1 tsp per 1 gallon of top off water shake and pour slowly into tank. Has any one else heard of this product. If so, what is it, think I heard it was made by Kent, not sure. Also is anyone adding kalk powder into ro water and pouring into tank directley. If so I would imagine it would have to be a very small amount of kalk powder. I know and understand the reccommended dosing procedure for kalk, but courious if anyone has experimented with other ways.
