With proprietary chemicals ...

With proprietary chemicals one would be best to follow the manufacturers guidelines.
If chemical compounds and concentrations are known, I would suggest to run PHREEQC models (available free from USGS website) to model your water and focus on the solubility indexes (to identify scaling issues) and the reduction potential (Eh, to identify corrosion issues).

Good thing about PHREEQC is that you can batch run mixtures of your source water and your additives to generate graphs you can use to identify optimal mixtures for your conditions.

Please note that -to the best of my knowledge- chloride and it's compounds are not included in their main libraries, so that may cause issues depending on your additive's chemical composition.
