my numbers after opening

[roady]

Hello,

I just opened pool and started filtering for a few hours without adding any chemicals so that I could post my opening numbers.

My numbers are:
FC .5
CC 0
TC .5
PH 7.5
TA 140
CYA lower then 20. After doing the test as directed I could still see the black dot. I bought the test set from here.

I have plenty of bleach on hand as well as 3" Trichloro tablets purchased from pool store and chlorine stabilizer (100% Cyanuric Acid).

The pool is inground vinyl aprox 20,000 with DE filter system.

Thanks for your help in advance. I look forward to learning this the right way instead of the pool store way.
