Need help with Pool Math app

Lei Mend

Hello, I’m new to using the Pool Math app. Is it normal that the app is saying the pH and Alkalinity is outside the ideal range even when it is within the target?
I’m using Taylor K-2006 test kit. I’m using 12.5% Liquid Chlorine for daily sanitation and a Cal-Hypo powder for Shock.

I decided to get rid of the Leslie’s chlorine tabs, Chlor Brite shock, Perfect Weekly combo when my water tested at 157 CYA level. It is such a pain to drain & refill (slowly) a 24,000 gallon pool!

Look at things like this,
The recommended ranges are really good for your pool. The ideal ranges are really really good for your pool. As long as you’re in one of the two, you’re golden.

Tap on the tile for each of the items that are showing that message. The ranges you see on the overview are the recommended. For example, PH you are seeing 7.2-8.0. If you go into the PH view, you can see at the top the Recommended range is 7.2-8.0 (as seen on the overview), but the ideal range is only 7.6 to 7.8
