Cya was tested at pool store with drops and under a lighted computer

first time test with TF-100

Not sure what to tell you. The Taylor chemistry is the most reliable test, and it's calibrated in bright indirect sunlight.
CYA test just takes practice. As was said above, test in bright sun light, turn away from sun and hold at waist level, looking down in. The great thing is you can pour the mixed solution back into the dropper and keep practicing till your confident in the reading. You don't need no stinking pool store, keep it up!
If you are going to try to test your phone functionality ... do it in Test Track and not here.

How should I lower TA
..... Add muric acid right

I suspect you'll be told to leave the TA where it is for now and only adjust it if you see your pH drifting up or down a lot.
Yes acid lowers TA, but also pH and yours is already at the bottom of the range. Just ignore TA unless your pH rises too fast.
You can learn how to lower TA in Pool School but, as suggested, just leave it alone for now and keep an eye on your pH......you may not have to touch either o
Water test tonight
PH 7.2
FC 5.0
TC 5.5
CC . 5
TA 120
So if I aerate tomorrow PH will come up to say 7.8.... If I add muric acid this will lower ph and TA right
When I tried to put figures in pool math it didn't say how much acid to add

why lower TA? It is in range. TA is a buffer for pH swings so leave it is my advice.
And ph is fine at 7.2, it will probably come up on it's own with splashing and such. Test your chlorine every day, the ph every 3 or 4, and TA weekly. Those shouldn't change much if all you are doing is adding cl to keep that up where it should be, which will be a daily addition.
My ph will continue to drop
We only swim on weekends it is covered during the week
I tried with pool math.. Nothing is in muric acid it is zero

That is because in PoolMath you have to use the pH values to lower TA. If you want to lower TA, lower pH to 7.0 then test the TA. Aerate to raise pH back up, then drop pH to 7.0 to lower TA again.
Why?
Add 0 muric acid
I would like to lower TA using muric acid
It says in Pool School: "There are two reasons to lower your total alkalinity (TA) right away, because you want to slow down the rate that the PH rises, or if high TA is contributing to a high calcium saturation index (CSI) which puts you at risk of calcium scaling. You shouldn't lower TA just to reach a target number. Make sure you actually have one of the above issues before lowering your TA."
If you just aerate the pool the pH will climb without raising TA. Adding anything to raise pH will also raise TA. You'll end up doing the yo-yo with soda ash and acid. Right now it looks like your pH is fairly steady and in a good spot, so there's no reason at all to fuss with pH or TA. When the pH climbs to 7.8, add acid to lower it, and it will also lower TA a little.
