About Orenda
Master pool chemistry with Orenda, a swimming pool calculator designed to help you balance water chemistry accurately. The app guides you through chemical dosing using the Langelier Saturation Index (LSI) method, so you can maintain safe, clear water without guesswork.
Whether you're opening a new pool or maintaining an existing one, the dosing calculator removes the complexity from water treatment. Input your current water parameters and pool volume, and the app calculates exactly how much chemical to add. The pool volume estimator makes it easy to measure your water capacity even if you don't have official specs.
Novice pool owners and experienced operators alike can achieve professional-grade results. Watch instructional videos built into the app to deepen your understanding of pool chemistry fundamentals. Orenda takes the uncertainty out of water care, helping you keep your pool in perfect balance all season long.
