Probably less than you can measure. E.g. 1 liter of 15 ppm CS would contain 15 mg of silver. Silver citrate contains 3 silver atoms for each citric acid molecule and the molecular weight of citric acid is approximately twice that of a silver atom. If you have a perfect complexing you would need roughly 10 mg of citric acid to convert the 1 liter of 15 ppm CS to silver citrate. 10 mg is hard to measure. So I would just add a pinch or more of citric acid and mix. Extra citric acid does no harm. Any old citric acid will do.
Citric acid has is very antimicrobial.

Hi Steve, Do you have any guidelines for how much citric acid to mix per volume of CS? Do you think silver citrate is still effective? Would I just google shop for any old citric acid?
