I’ll test the CC’s now. The water is pretty clear, but was fairly clear when I began, and it got a little cloudy when I put in the SLAM dose of lc 24 hrs ago now.
Cannot get a Chlorine reading

Fc should fall pretty quickly at such high levels. I just saw it myself doing an insurance slam. My 3 to 4 ppm daily drop spiked to 8 ppm a day in the high 20s.
Test it daily and watch it fall to confirm your original measurements were correct.

Water is looking good!. Have you cleaned out the inside of that ladder with a brush and chlorine? Same for the steps, those are good hiding places for algae.
I'm very glad I don't have any pine trees anywhere near me. Those do look like a pain.

What level do I need to let the FC drop too before it is safely swimmable?
I just tested again and FC is 27.5 and CC 0.5. My SLAM is 28. Should I add the 13 oz of Chlor to bring it back up to SLAM level, and make sure that it holds overnight?
27.5 is plenty close enough. Test it after it gets dark for your overnight baseline. Whatever it is, is fine for tonight.
The water tested at 20FC last night and 20.5 this morning. Now, I guess I just need to maintain?
Assuming CC is still <0.5 and water is still clear, then yep.
Also, ph test isn't accurate above 10FC. Once you get down to around 9FC, test it as it's been a while and you may need to add some acid.

Ok. Now I’m nervous. When I tested last night at 11:30pm, my FC was 19, and my CC was 1
. I just tested now at 10:00 am and my FC IS 17.5, and the CC IS 0.5. Should I bring it up to SLAM level again?

We can't say without a proper OCLT. You've lost some FC today, but exactly how much is anyone's guess.
But you passed yesterday's OCLT so you're probably fine.
In a worse case scenario you won't go backwards so long as you're free and clear above min FC at this point. If it turns out you see excessive loss when you're back in target range, it was only a pause in the action if you need to SLAM a bit more. But again that's worst case and with yesterday's OCLT pass, and a late test this morning with little loss, it's likely good to go.

Ok. Thanks. So I’m safe to turn off the filter and give the pump a rest?
*worth noting, commercial pumps that never shut off last decades. The filter doesn't care either. Your electric bill is the only thing you need to rest if you have a single speed pump. 
With a VS pump, it can run so low it won't make or break you.

Thanks. Will probably replace it with a variable pump when the is one kicks.*worth noting, commercial pumps that never shut off last decades. The filter doesn't care either. Your electric bill is the only thing you need to rest if you have a single speed pump.

A single speed pump is far less expensive to run than HVAC. If I do decide to upgrade a VS is certainly on the list.*worth noting, commercial pumps that never shut off last decades.

Amen to that. If my VS pump adds $10 more to the $510 summer month electric bill to run it 24/7, I don't even know it could have been $510 running the pump part time.
In the 2010s my friends with SS pumps cost them about $100 a month to run by comparison. Rates have been mostly flat since then so I imagine it's similar today.
