How to Use the Orenda App

May 15, 2017

 UPDATE, June 2019: The Orenda App has grown to become one of the most popular and widely used swimming pool apps in the world. We are grateful for all of our users, and are pleased to have created such a valuable tool.

This article will walk you through how to use our app, the LSI Dosing Calculator, and other features.

LSI/Dosing Calculator

App with 600 CHThe dosing calculator is the core function of the Orenda App. Without a doubt, it is the most widely used chemical dosing calculator app on the market today, and a big part of the reason why is the simple user experience.
  1. Select the type of pool you have under "calculator type", be it residential or commercial.
  2. Input pool volume in the top right bubble.
  3. Adjust the dials by touching the number and dragging your finger left or right until the desired number is on the screen.
  4. Input the current levels of water chemistry parameters on the left side of the calculator. Be as honest and accurate as you can with water testing.
  5. Input the desired levels of water chemistry on the right side.
  6. Tap Get Dosage and you will go to the dosing results page.
    1. The calculator is just a computer. For example: if you are adjusting both alkalinity and pH, it will give you two numbers for both changes. Adjust alkalinity first, then re-test pH and make a further adjustment if needed. The calculator only knows how to go from left-to-right (current levels to desired levels).
    2. If you use Orenda Products, the doses are at the bottom of the dosing results page.

LSI Color Code

Be mindful of the LSI value at the bottom. We strongly recommend maintaining LSI balance year-round. 0.00 is perfect, but we have color coded the calculator to encourage slightly above-zero chemistry, so the LSI number is green. In fact, the action step for our First Pillar of Proactive Pool Care is to maintain a green-colored LSI on the Orenda App. The colors of the LSI are as follows:

  • +0.31 and above (purple) - Over +0.31 tends to be a scale-forming chemistry. This is an over-saturation of calcium carbonate. While carbonate scale does not necessarily harm pools or equipment, it needs to be cleaned up and ideally prevented so that it does not block up equipment (like salt chlorine generators and pool heaters).
  • 0.00 to +0.30 (green) - This is the sweet spot of LSI balance. We want you to be balanced in the low-green area, which provides a bit more cushion and protection from permanent damage caused by aggressive water. Maintaining 0.00 LSI would be great, but factors like pH fluctuate all day, so the best policy is to aim for the green and try to stabilize it with a good foundation of calcium hardness, which will not fluctuate much at all.
  • -0.30 to -0.01 (yellow) - Yellow is safe, but a warning. Unless otherwise specified, try to avoid the yellow and stay in the green. An exception to this is when using a chlorine like Cal Hypo, or when you are trying to clean up carbonate scale. If you need some room to dissolve visible calcium into solution, you want to be in the yellow to help speed up the process.
  • -0.31 and below (red) - Red is under-saturated, aggressive water. This water is corrosive and will etch pool surfaces and dissolve calcium wherever it can be found. This is the water that fades vinyl liners, causes calcium crystals, destroys equipment and is responsible for a significant number of plaster problems. Avoid aggressive water at all times. The damage it creates is permanent, unlike the opposite problem (carbonate scale).

Pool Volume Estimator

The pool volume estimator is an experiment in math and patience. We designed it to follow the NSPF's Certified Pool Operator (CPO) Handbook's formula for estimating pool volume. It is perfectly in line with those formulas, but no pool is perfect. How do we know how much slope the deep end has? How curved is curved? Is it really a perfectly rounded cove? Pools nowadays are unique water shapes, so this tool is really only for estimation purposes.

  1. Select the general shape of the pool (circle, oblong, rectangle)
  2. Either type in the dimension by tapping the number and replacing it, or by sliding the dial until the number is reached.
    1. For large pools, you will need to type in the value, because the ranges on the slide dials are made for typical residential pools. The estimator will still work for larger pools, but you must manually enter the dimensions if they exceed the dial's range.
  3. The bottom will show a real-time estimated volume of the pool.

Orenda Products

Orenda Products are featured in the app in case you need more information about them. Each product has its own tile that can be tapped on to open a product page. The product page has a link to the SDS sheet, as well as a link to this website's full product page, containing how-to videos and more information.

App Settings

When you first open the app, you will be sent to this settings page. You must select your language of choice and units of measurement (US Imperial or Metric). We currently offer the app in English, Spanish and French. We are open to adding more languages, so if you would like your language represented, let us know.

The units of measurement was a challenging thing for us to create because we are Americans with almost no concept of the metric system. It is kind of funny how many revisions we had to do, because calculating Imperial to Metric is no problem...it's finding every item in the app that must be converted that we struggled with. We had volumes converted from gallons to litres without a problem...but forgot to convert Fahrenheit to Celsius. Then we forgot the change the actual temperature dials from Fahrenheit to Celsius, which made the Metric system calculator go haywire. We think we have it figured out now, however. If you do find an issue with the Metric system, please contact us immediately so we can get it fixed!
