I'm still gathering information, and perhaps people here will be able to add info on the current salt list (to fill in the holes) or additional salts not on the list. Right now, the page is non-editable. Eventually, I'll get up an editable page where you can enter in your own target salinity and the price you pay for salt.
The results may surprise some of you!
