It looks like the amount it gives is too low. See the attached file.

You need a TA of the water to calculate how much acid to use to lower pH.

You did not test for TA as there is no valve for the Alkalinity. You have to add that to be correct.

Also make sure pool volume (gallons) is set correctly in the app.

Thanks. Once I input the TA number, it works fine.

By the way, what’s the limitation of free version?

IMO, the main one is - It will only save the latest test results. for $8 per year - it is well worth to have the fully functioning app.
