The pool math app is saying to add those things based on my most recent test results.
Ignore it. Pool math has "recommended range" that's the one next to your reading. See how your FC is outside of it? That's not good. Then there is "ideal range" which is what the warning is about. You can turn this off or simply ignore it.
