Water Treatment for small steam boilers in apartment buildings

Hello; I have seven small steam boilers, 210,000 to 400,000 btu and I would like help in deciding water treatment. My supply house, Famous Supply does not recommend Culligan, and Culligan wants 4 grand per building. We put tablets in each year throughout the year and flood at end of season. More suggestions?

    Before being able to really make a suggestion, two questions: what is your feed water quality, particularly hardness and chlorides (NOT chlorine -- chlorides) and how much of it do you feed?

    That asked, generally speaking if the water is nor particularly hard and the feed rates are reasonable, the only treatment I personally feel possibly needed is buffering for pH control.
