Hello! First time opening a pool. Also, first time attempting to balance chemicals using the TF-100 test kit plus the Pool Pal mobile app.
I have quite a few questions (the questions are highlighted in blue), so thank you so so much, in advance, for any help with the following....
I have configured my app as shown in this first pic. I am not completely sure I have done it right. My biggest concern is the baking soda. The app only lists these two options: washing soda, and soda ash... and I'm not sure which one to select when using the arm&hammer baking soda.

Next, I'm not sure which chemical needs to be balanced first. In case it's important, know that our pool had quite a bit of fine dirt and silt that we had a really time hard vacuuming up... but that has almost completely cleared up finally. The pool is still very foggy, but a white fog, rather than a green one (which it was when we first started).
So.... I understand (I think) that ph should be balanced first. The only problem is, my app is telling me to increase the baking soda (washing soda?)... but then at the same time, it is telling me to decrease the ph in order to get my alkalinity in check. So, what should I do first?
When I first opened my pool, I did not yet have the test kits, so I brought my water sample to a pool store, where they said my salt was at like 2700 they told me to add 50 pounds of salt to reach my goal of 3300. But I only put in 40 pounds. Then... now I have my test kit, and I am using the Taylor K-1766 salt test. It reads that my salt is now at 4000. I have retested 3 times and it is always the same. Should I trust the readings I am getting with the K-1766 test... or should I be concerned?
Here is the results and the suggestions of my Pool pal app:
Can you also please tell me what the last two sections of the readings mean? What is CSI and LSI? It says that the results are corrosive? What do I do about those readings?
Thank you again!
