Which issue to correct first

[tobydog]

I haven’t stayed on top of the pool chemistry like I should have been. Tested the water today and got these results. Which issue is best to tackle first?

FC .5
PH 8.2
TA 130
CH 400
CYA 25


The pool is about 25k gals with white plaster and liquid chlorinated.

You need chlorine. Then lower pH into the 7's.

Do an Overnight Chlorine Loss Test tonight.
