TFP App is freaking out!!

Garbage in, garbage out.

What did you enter to get that?

Post screen shots of the app.
 
Why are you targeting a pH of 3?

And how do you have a TA of 35?

Those values make no sense for pool water chemistry.

I am not changing the target of any of the chemicals. I always just rely on the app. I was under the impression TA for a vinyl above ground pool is unnecessary. We have not tested TA in 2 years and therefore have not changed the values (on purpose at least).
 
The level of TA is necessary to calculate the pH effect of adding acid. You should always test TA when you have a pH you wish to adjust using acid.
Someone changed the pH target to 3. The app does not select that value.

Ok, gotcha. I changed the Target pH to 7.6 and now the recommended acid looks typical. We will also begin testing TA again as well. I appreciate your patience and help.
