Do you add calcium in a salt form? Have you considered blending your RO feed with the permeate? This seems somewhat counter-intuitive but will be much cheaper on chemical addition, produce a greater quantity of water and probably achieve a similar water quality, particularly if youre pre-treating with a reasonable Activated Carbon filter...
