That would be nice, but unfortunately JasonLion, who created it, not longer owns the rights. It sounds like you are on top of the chemistry, so maybe you don't need it? In my case from my very early usage I didn't even choose a suggested goal level category when I used the poolcalculator since i knew from reading what I wanted for targets.
In terms of CH, you don't want it too high since that can cause scaling on the heater. Generally having it low is not a problem unless your tub surface is fiberglass and then you just need it above 100 ppm. Also, sometimes foaming can be eliminated with some additional CH (100-150 ppm). What is your tub surface? What is your CH?
