Step-by-step instructions

1. You’ll first need to activate this feature and configure settings on the website, after which these new options will appear on your app. You can use it anywhere you enter readings and dosages. Using a route stop, scroll down to Readings. The categories necessary for LSI calculations are marked. If we want LSI, we need to enter a value for all six. Free Chlorine and Borates are optional.

2. Scroll to the Orenda calculator. Previous shows what LSI was calculated during your last visit, but since this is the first time for this customer, it shows as None. The number we’re paying attention is in Current. As you enter the readings, calculations are being done in real-time, and the results will be displayed here. So if you were to change pH from 7.5 to 8.0, the Current number will change as a result. This is built into the Skimmer app and doesn’t require an online connection.

3. The pH is a little high, and you want to get that number down. Click Calculate to bring up a screen with Current readings on the left. On the right, you have Desired readings, or what you want the readings to be. Tap to reveal a slider with values to choose from. You want to lower the pH, so tap on pH and move the slider so you can choose the number you want to achieve. When you chose that value, the projected LSI number in the desired column adjusted. For demonstration, let’s also change the Free Chlorine desired 4 to 5.  When ready, tap Get Dosages.

4. On the next screen, you have two sets of dosing recommendations – one to decrease pH and another to increase Chlorine. The system provides multiple methods so that you can choose the one that matches how you work and what chems you like to use. This will reflect the choices you made on the web when you set up the feature. After you make your choices, the Apply button has changed to show that you have two dosages pending. When ready, click Apply.

5. Back on the main screen, the current value still shows the LSI reading you don’t want. The water chemistry hasn’t actually changed yet, since you’re just adding the appropriate chems. Scroll down to Dosages, and the chemicals you chose in the calculator have been entered. From here, do whatever else you need to do, and when you’re ready, tap Finish. Now that record is saved. Next time you come back, what you calculated as the Current LSI will show in the Orenda box as the Previous LSI. So when you take the readings again, you’ll be able to compare and easily determine if the water chemistry has improved.
