I apologize- I keep meaning to log it but I have been jotting it down and just keeping track that way. Working from home & home schooling I’m lucky I can keep track at all!

So with my 30 cya- I shouldn’t be concerned losing fc like I have during the day?

From here I should let the fc drift down to an appropriate range and then do a full test - first adjust ph- then adjust stabilizer?

Right. Keep FC in target range for your CYA. Use FC/CYA Chart

Add 10 ppm of stabilizer via the sock method. Test for CYA a day or two after the material is fully dissolved from the sock.

Hi. I didn't turn on the chlorinator yesterday after thinking i completed the slam and i just let the fc drift down. i checked this am at 4am and fc was 10.5 that was a 2 ppm drop from 820 last night. i let it go all day without adding or turning chlorinator on(80 degrees , full sun all day, water 73 degrees) and this is what i got at 5:15pm
fc-5.5
cc-.5
ph-7.5
TA-130
CH-100
cya-30
csi-.43

So now i'm wondering if i should bring it back up to slam level since the drop overnight was more than i anticipated. the pool water is very clear, i can see the very bottom and every nook and cranny perfectly.

what would you recommend to do at this particular point?

Ok but that being said, I forgot to turn my chlorinator back on- so no chlorine went in. Considering temp (80 degree day & full sun) and having just completed a slam- should my fc have dropped from 12.5 8pm Thursday to 5.5 at 5pm Friday? That’s my concern. Is that too fast of a drop ?
