b) from about 40 to about 600 ppm of a first polymer comprising:
i) carboxylic acid monomers;
ii) monomers comprising a sulfonic acid group wherein the monomers comprising a sulfonic acid group represent more than 10% of the polymer on a molar basis;
c) from about 15 to about 150 ppm of a phosphonate;
