Im still interested in this as well. In my case, vinegar spiked saturated kalk will not maintain Ca/Alk levels and a Ca reactor is not an option. Consequently I dose both CaCl and baking soda daily to make up the difference.
While I understand all the anti CaCl arguments in the previous thread, I agree with Victor. In a maintenance scenario one would also have to use an alkalinity additive as well, this usually means a sodium bicarbonate based product so Cl levels relative to Na levels will not change nearly as much given the addition of the sodium component.
Sure the ratios are not going to be exact and you won't be getting some of the secondary ions but IMO CaCl products have their place in a maintenance program combined with a sodium based alk additive, kalk, and regular water changes for larger tanks with increased calcium carbonate demand.
If the benefits of balanced two-part additives can be mimicked with RHF's recipe without the prohibitive cost for larger systems, even better.
