@Mdragger88 I cleaned the drain cover the best I could. No lights in the pool, so nothing to clean there. My CC has been 0.5 for a while now, and I've passed the OCLT multiple times, so I've just been waiting for the water to be perfectly clear. And I'm happy to report, today is the day. I will try to get a good picture (it's pretty breezy today, which is making it tricky), but the water is absolutely crystal clear. I swear, I could drop a dime into the bottom of the deep end and still be able to read the date on it.

CC 0.5 or lower

Passed OCLT

Water is clear
I am officially calling this SLAM complete! For good measure, I topped my FC back up to 16 one last time this morning, and now I'll let it drift down to normal levels. I really appreciate all the help you all have provided - turning my green, nasty swamp into a beautiful backyard oasis (or something like that). Can't wait to have friends over and start getting some good use out of it!
As I shift my focus to maintenance mode, I have a few questions (I am planning to follow the
Basic Pool Care Schedule from Pool School).
1. For my daily FC tests, do I continue using the FAS-DPD test, or is that just for testing and maintaining higher levels of chlorine?
2. I currently have my robotic pool cleaner running daily (2.5 hours per day). Is that necessary, or should I scale back to weekly? I don't get much debris in my pool at all.
3. I currently have about $200 worth of powdered shock and chlorine tabs from the pool store. Will I ever have any use for them, or should I just let it go and accept the loss?
