Thank you for your support folks...
Do I need to SLAM my pool?

Heck yeah. My hand gets a little shaky at drop #15 of 60. It’s not that you’re doing anything wrong Alex, It’s just probably that you’re human too.
let it drift down and see how it goes.
Looks like I'm keeping FC today during the day. Did I mention that I have sun all day long? But my SWG is running at 100%.You're doing a great job and have been super vigilant.We have seen where exceptionally high FC levels can sometimes have some erratic testing behavior. Add to that it's simply exhausting to count FC drops at numbers as high as 60, 70, etc.
Based on your water condition, filter, etc, I'm comfortable letting your FC drop to around 20 and doing a new OCLT at that lower range. Let's see if you receive a more consistent result tomorrow. Fingers crossed.
Then it could be a false positive and why we always say to shut it off for the SLAM. It’s too hard to track what it, the algae and the sun are doing to each other.
*not gonna hurt you here today, as you were going to drift down anyway with the pool and filters being so clean, but just pointing out what might not be obvious.

Yeah, I would turn that off. Otherwise your FC won't fall to the ~20 range we were hoping for to do the OCLT. If it doesn't you'll have to leave it off and try again tomorrow.
I didn't use SWG yesterday, only LC. Today decided to use SWG to help along.

Great, then I would continue to leave things the way they are right now. No chlorine today and don't turn on the SWG today. You have a starting FC of 25 today, and you "should not" drop below 20 - 21 today. So no chlorine today. Test the FC this evening and do another OCLT if you can. Ideally I'm thinking your FC tonight before bed should be about 21, then hopefully you won't lose more than 1 ppm by the next morning. Since your last OCLT was much better, I'm thinking your pool was struggling to maintain such a high FC level and it had nothing to do with algae, but let's see how it looks again tomorrow morning. For today, do your normal cleaning and enjoy your pool. 
Good estimate sir. I just tested and FC is at 21ppm. And we were swiming for a bit too.Great, then I would continue to leave things the way they are right now.

Yes. SWG was off.
This morning FC is at 18PPM....
Also pump was running for about 30 min before I took a sample.

Good morning! So yesterday's daily FC loss was normal and as expected (4 ppm w/ swimming). But the OCLT failed (21 - 18). TFP advice would normally be to remain at SLAM level and continue. 99.9% of the time that's what we would say. But you've been stuck for a while. Your water looks immaculate, your daily FC loss is acceptable, and your overnight FC loss is less now than it was when you were trying to maintain a higher FC at night. With no lights, steps, or other potential algae hiding places in the pool, and a robot to keep the surfaces scrubbed, maintaining the SLAM level doesn't seem to be productive right now.
I'm more inclined to recommend leaving the SWG off for yet another day or two. I would expect an FC loss of about 4 ppm again today, bringing your FC down to about 14 by the end of day. So let's do that again today - take another break from chlorine. It would be nice if you could do another OCLT tonight, although you might be getting exhausted form those. But if the pattern holds true like last night, I'd like to let your FC eventually fall to about 10 or slightly below so you can do an accurate pH test. So here's what I would like to see:
Monday: SWG OFF, starting FC goes from 18 to about 14 at night; do an OCLT.
Tuesday: SWG OFF, starting FC? Ideally 13, but might be 11-12 based on recent overnight drops. By end of day FC about 8-9 ppm. Test/adjust pH and do an OCLT.
Wednesday: Report card day. Post back with OCLT results. Will probably turn-on the SWG at this point and reevaluate everything.
While you (and your SWG) enjoy the break from chlorine additions for a couple days, continue with inspecting and cleaning any areas your robot can't reach just to be safe. I think the only place you might have like that is the skimmer area (weir door, backside of flap, etc). I'd be curious to see how your FC goes the next 2-3 days. If you see a large drop in FC between now and Thursday, something larger than what I predicted above, let us know and we'll reevaluate. Good luck and have a nice day.

Understood. Thank you for your detailed response. I will follow your recommendation and will report back.

Gorgeous pic, but I'm a little concerned about that FC drop today (more than 4 ppm), especially since you had a cloudy day with some rain. Let's see what your OCLT results show tomorrow morning and we'll go from there. This experimental break in chlorine may be short-lived. We'll see.
Since everything appears to be very clean, clear, and well maintained, let's recap the FC test. I know you're doing the 10 ml sample size with one generous scoop of powder. As you stir and add the drops, be sure to turn the bottle of R-0871 completely vertical and keep a good steady pace of drops - about 1 per second or so. You shouldn't have to squeeze the bottle to make the drops come out, they should flow quite well with very little pressure. We're at a point we need to be extremely critical about everything you do, otherwise it's back to the drawing board (pool) and algae somewhere.
I have a doctor's appt early in the morning, but I'll catch-up with your OCLT results as soon as I can.

- It was mostly a sunny day with rain arriving around 5 pm. It probably rained for an hour but was cloudy the rest of the day(daylight).
- I'm doing a 10ml sample but I use 2 leveled scoops. I'm pretty sure this is what Taylor kit is calling for. Yes, I do keep the bottle vertical.
- I will do the morning test around 7 am EST.
Thank you for your patience Texas Splash.

Taylor speaks of 2 scoops when doing the 25 ml sample size. Since you are doing 10 ml water sample sizes, you get by with just one generous scoop of powder. It's an accurate sample size amount and should save you some powder over time.
