Levels okay but CSI -0.75

[Ryan-Cal]

We had insane rain in SoCal and my pool turned into a lake briefly, but a quick SLAM made it crystal clear. My CYA is badly deficient and I need to get on that, but my balance is better than it's been in years and my CSI is -0.75.
1) do I need to worry about the CSI or just be patient and let time pass?
2) if my CYA improves, will that fix the CSI?
3) I need to add almost 6 lbs of dry stabilizer. I've never had much luck with it. I committed the mortal sin of dropping it in the skimmer once. Then I added in socks into the skimmer but making sure that I didn't cut off the flow of water. Is there a solution out there that doesn't require an elaborate setup and will dissolve in a reasonable amount of time, should I just stick with the socks, or should I drop the big bucks on some liquid conditioner?
Thanks,
Ryan

Attaching photos from last Saturday and today. Had to pump out tons of water because we don't have overflow drains here in socal. So odd.

Your Poolmath logs show various results just done. The CH is fine (either one). So the CSI is low due to lower TA and pH with low water temperature (your last water temp entered is from a couple months ago). Let the pH rise and it will be fine. TA will increase once you start adding fill water again.

Thanks. You're right. I had messed up the first CH. I figured out how to delete the measurement.

Just checked the pool temp, and it's 5 degrees warmer than I thought, so I'm closer to the right range.

Thanks again for your help

Don't know whether you'd consider this an "elaborate setup", but I use a sock hanging from a wire coat hanger in front of one of the returns, with the hanger anchored by a 5-gallon bucket filled with water. Periodically squeezing the sock makes it dissolve faster.

If you do this, don't just tie the sock to the hanger, because the knot will loosen. Stab the hanger through the sock like you're baiting a fishhook, and bend the wire to ensure that the sock can't slip off.
