The Orenda App calculator gives regular chemical doses, as well as doses for Orenda products.
Use the LSI/Dosing calculator normally and include your pool's volume in the top right corner. When you tap "Get Dosage" at the bottom, you will see your various chemical doses required (i.e. acid dose, sodium bicarb, etc.). Scroll down to the bottom of the dosing results page to find Orenda products and their doses.
