TA reading etc

New to TFP. But JohnnyB is helping me.

First test 3.20.2021

630PM

pH 7.2

FC 33.5, been using bags of shock from pool store

CC 0.5

TA 240?

CYA >100

Added pH up this afternoon- Johhny B will coach me in the future

We ignore pH reading while the FC is so high, right? We re-test pH once the FC falls to the 11 range?

TA- never turned red, only went to light yellow at about 9-10 drops & didn’t change much thereafter so we just stopped at 24 drops. What’s w that?

CYA- been using pucks, want to transition to BBB/ TFP system. Will order a proper test kit soon, using Johhny’s for now. How do we handle such a high CYA? We know the range should be CYA 20-50 . Need we deal with/lower the CYA?

Thanks

Welcome to the forum!
If your CYA is greater than 100, you need to exchange / drain and replace some water.
Do a CYA test tomorrow with your pool water cut 50/50 with tap water. Then use that mix for your sample when doing the CYA test.
Your TA test was effected by your high FC. Read Total Alkalinity - Trouble Free Pool
I suggest you read ABC's of Pool Water Chemistry.
