I shocked the pool and the next morning I had a
10-fc and by today I have
1/2 fc and 0-cc.
ph-7.3
alk-60

I did get some cya today but now my ? is how much do I put in a sock in the skimmer? I assume the cya is not stronge like the trichlor pucks that I had confused with cya. My pool holds 25,700 gal. I have 0 cya. I do have 2 trichlor taps in tha automatic dispenser on the pump. I have waited till tonight to add my bleach to bring up the FC. Also I am slowly adding baking sond to bring up the alkalinity. Thanks for any help. Sharon
