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.

It's OK to use Trichlor for a while--you need some CYA and your pH is OK, but if it drops a little, no harm. But watch your CYA levels and pH to see that the first doesn't go above 50 and the latter doesn't go below 7.2.

You need to get your FC up, though.

Thanks CarlD for your help.

Last night we dumped in 6 galllons of bleach and left the filter run all night. The pool still looks the same nice and green. We tested for TC this morning and it was .5.

I just figured out that I posted this in the wrong forum though. We have the TF-100 test kit. I will repost in the correct section.
