Alright I'll add the LC tonight, retest and get up to level throughout the day tomorrow, and find some muriatic acid and more LC tomorrow evening. Can I add the MA any time between leveling my SLAM?

When you initiate a slam you add what poolmath advises then check it 15 minutes later to see if you hit the slam level. If not add to reach the slam level again. Rinse and repeat till the first time slam level is achieved. Then you can take a 3 hour breather and Check/add back what's missing to hit slam level. As the slam continues it'll take less frequent topping off till it'll hold it completely.
So I got up this morning after the initial LC add and the pool looks visibly better. I did the drop test and my solution won't turn clear from pink. I'm 60 drops in at this point which doesn't seem right.
What was the FC last night ?
How much bleach did you add ?
10ml or 25 ml ?
Did it sit for a few seconds clear, go pink again, and you kept going ?

Last night it was 0 and I added 461 oz of 10% liquid chlorine which should've brought it up to 17 ppm. This morning I added 1 scoop of the powder to 10ml of pool water and it turned a very dark pink. Unable to get it to go clear.
I never like this. I like 'I added 3.5 jugs'. It's way easier to math wrong when its 461 ounces.
You can do a 5ml sample and each drop is 1 FC.

Also to note, this is the first "real" test with my new replacement testing solvents. I did the initial test, and posted my results above, and I expected my FC to be 0, so I didn't have to really use the R-0871. So I'm hoping my replacements are good and that isn't the issue.
There have been some tip issues. If you can swap with the old tips, do that. If not wipe the new tip after each drop and a few tests later that static charge will be gone.
Ok so I replaced my tip with the old one and wiped with a damp cloth between each drop. I also tried the 5mL test with the same results. Solution goes very dark pink or red and never lightens up. I saw another thread on here about that happening when CYA was low so I also checked that, and it appears to be 50/60. Admittedly I'm not confident with my CYA test because it's hard for me to judge when the dot completely disappears. When I checked last night it was 40 and I've had to add water this morning because I did a quick backwash to try and remove algae debris from the filter, so if anything I assumed it would've went down not up. I want to add LC this morning to keep my SLAM level up, but I just can't seem to get a FC reading.
Ok I went back and overly cleaned the chlorine test tube and made sure to take my time when dropping the solution into the cylinder and was able to get a FC reading of 12.5. Maybe I was dropping the R-0871 solution in too quickly before, but I made sure to hold the bottle completely vertical and let gravity do the work. Definitely took longer but appeared to generate results. I added the recommended 203 oz (or a little more than 1.5 gallons @Newdude) and will test again in a few hours. My water line is barely above the skimmer line so I do have a hose running to refill the pool back up so there is a decent amount of water in the skimmer baskets.

There are no prizes for being done in 9 seconds. You will not ever miss 20 more seconds. I promise.
Could have been the dirty vial too, or both. Either way, woohoo.
But yeah. I get wonky results from time to time and taking a deep breath and slowing it down fixes 99% of them.
There are also no prizes for measuring 203 ounces in 20k gallons. Eyeball it and add a few extra glugs just to be certain.
Not...going...to...say...it...I can't help myself. I'm an engineer and my OCD demands precision. It's a blessing and a curse.
GREAT. Road test both ways and see how you cant tell the difference. *if* you see it, its because of the 1 drop test variance and it wasn't you.
Plus like I said, I'd rather have 227 or whatever my slight overestimation was than 203. What if poolmath's rounding error to 20k gallons was a hair low? What then ? Being under would keep me up at night. We all have our thing.
Tested again 2.5 hours after my last LC dump and my FC is still at SLAM level. I went out and noticed the entire floor was murky so I brushed the whole thing (previously I just brushed the walls, steps, ladders, and weir doors since that's what I could see) and I kicked up a bunch of junk. Am I right to think my FC didn't drop a bunch because all of that stuff was caked to the bottom, and kicking it up will give the LC a better footprint to be used? I'll check again in 3 hours when I'm off work, but I didn't add any LC since my levels were still at SLAM level (I tested twice to be sure).

No, likely you just killed everything.
Post a few pictures of the pool, include ladders and light in the pictures.

Sorry, I actually meant to post these pictures with my post. If you notice those plastic stairs in the back are screwed down and then removed in the off season. I actually hate them because stuff can get behind them all the time and I don't have anything that can get in there to scrub/vacuum/charge rent until it leaves.

Take those ladders out of the pool and scrub INSIDE them with bleach/water solution...ask me how I know...
I got this. https://www.amazon.com/dp/B003Q8GCGO
If you have a light, scrub behind the light. If you have a main drain, you need to remove the cover and scrub in there. Don't do it if you cannot see the bottom of the deep end...wait for it to clear a bit.
See post #8...slime in the ladder caused me an extended SLAM.

SLAM, Rain, Dissapointment.
In the middle of SLAM. Pool clear CC = .2. 2 nights ago OCLT FC loss was 2.5ppm. Next night, OCLT FC loss was 1.5ppm. Last night was 3ppm loss. It rained all night. Must have brought a lot of chlorine eating Crud out of the air. So disappointing.

So take the steps completely out as well? Or just the ladder?Take those ladders out of the pool and scrub INSIDE them with bleach/water solution...ask me how I know...
