Add it all at once. Brush before or after. Test again in 2 hours and see where you are.
Chlorine/CYA Issues

Okay, added all the chlorine. One last question. I saw in one place it said to turn off the SWG during the SLAM, but in another it said to run it during the SLAM. So, should I turn it off?

Turn it off. It does not add enough FC to matter, and it will skew your readings. We like to monitor the FC drop organically to determine how well your SLAM is going. Keep pump running 24/7.
Test in 2 hours and report back. Also, how are you doing on reagents? You will use a lot during this SLAM so you might want to order up some more.

At SLAM levels of FC you can use the 10ml sample size to save on reagents. In a pinch you can use the 5ml sample but that is degrading the accuracy. For an OCLT switch back to the 10ml or 25ml test.
Okay, thank you for the advice on the testing. My kit is only a few weeks old, so I'm pretty good on reagents, but I may order some extras of a few things just in case. And I've got the chlorinator off (turned it off last night, so just wanted to make sure I should keep it off) and pump is set to run 24/7. Thank you guys!

Ok, that is a big drop. Let’s try this add what pool math tells you. Wait 20 minutes for it to mix (help that with a brush). Then measure. Try using a 5ml sample. It will be less accurate, but we are just trying to hit a barn for now. Make sure that you got all the way to 31pmm. Your chlorine might not be as strong as you thought. We need to make sure that you reach SLAM level. If you are short after the 20 minutes we need to adjust the amount you are adding.
After you get to 31. Wait 4 hours and test again and adjust.

Sorry - just got out of the pool from lessons and tested and it is 8.4. I just brushed again and I'm about to add what pool math says to add and brush around. I'll check it again after 20 minutes. Thank you!

No, I had to stop adding after that first reading at 16.4 because I had kids coming to swim and I didn't want to add chlorine right before they were getting into the pool (I have some floaters that are only 12 months, so didn't want to cause them any issues). I just picked up more chlorine and retested the CYA. I think the CYA is actually closer to 70 now that I did the test in better lighting. So going to try
Okay, got it up to 27. Sorry got caught up with bed time, so I couldn't do exactly at 20 minutes after adding the chlorine. I'll test again in a few hours.

If you got to 27 in a shorter period of time than 20 min thats ok. At 70 you SLAM level is 28. Make sure you get it there before you go quit for the night.
Well, it was longer. I didn't get to check until an hour after I added the chlorine. And will do, thank you!
Okay, after adding chlorine in a few more times over the past couple of hours, I slightly overshot it. I'm at 29 now. Going to leave it alone and go to bed and see where we are in the morning. Praying I pass the OCLT!

Its too early to try to pass an OCLT. You need to be testing as often as you can and maintaining that SLAM level.
How does that water look. Is it crystal clear? Also what type of lights do you have in the pool? If they have a niche did you remove the lights and brush the niche. Make sure you brush the inside of your skimmers.

Okay just tested and I’m at 20.5. I’ll start adding and testing again. The pool looks completely clear. My lights are LEDs and are built into the wall and don’t have a ring around then to remove. I did brush inside the skimmers area, but not inside the skimmer basket part, should I do that?

Is that a ladder on the far wall of your picture? If so, those can be notorious for holding algae.
It is an artificial edge swim bar that I use for lessons. I actually just thought about that too, and so I picked it up out of the pool. Will being out dry in the air kill any algae on it?
I actually realized there was a gray scum on the pool bar so I just scrubbed it down with bleach to be on the safe side.
