You do not appear to be using PoolMath correctly. The left column is your NOW test results and the right column is your TARGET. If your target pH is higher than your now pH, of course it says 0 acid.
first time test with TF-100

- Start date
Assuming your CYA is truly 40, FC 3 is the minimum, add bleach.
I would suggest re-checking your CYA levels (using your test kit) during the daylight.

Whatever the jug says is the strength is what you enter. There's no point plugging in 22 Baume and spending a week hunting for it. Go buy the strongest muriatic acid you can find and use that value. Normal stuff is 20 Baume. The "low-fuming" stuff is 10 Baume.
