Why are chlorine and phosphates beneath the LSI on the Orenda calculator?

Chlorine and phosphate levels do not impact the LSI

We have chlorine and phosphates beneath the LSI in version 3.0 of the Orenda App. Previously, the LSI value was always at the bottom of the page. But since chlorine and phosphate levels do not impact the LSI, we decided to move them below the LSI to reduce confusion.

The Orenda Calculator still includes them, however, because it is a dosing calculator. Our dosing calculator shows both liquid (sodium hypochlorite) and cal hypo (calcium hypochlorite) dosing options for chlorine. Phosphates, however, will only impact the "as needed" dosing for PR-10,000, shown at the bottom of the dosing results page.
