I dose kalk via my ato, everything is doing well the only question I have is regarding the undisolved kalk that settles at the bottom of the 5 gal. container. Once the ro/di water is depleted from this container is it safe to leave the old kalk in there prior to adding more ro/di water and kalk or do I start with a new batch of kalk ?
