Forgot to mention that CLR can be used to remove mineral buildup in the system too but like the rest, use sparingly and only when cleaning, not as an additive you'd normally want in the system when running it.
I'm not aware of any problems with it reacting to metals or other materials you'd have in your system but check that before using to be sure.
