Strange FC Readings During Slam

I dont want a repeat where I passed 1 oclt and started over
This is why the extra day of SLAM is super helpful. And passing the OCLT means you should only have normal daily loss today, which will be easy to manage.

In theory you can raise the CYA as you are officially done SLAMing and only continuing for good measure. But if you need to extend the SLAM it will be at a higher FC. Normally it's a one and done but this one has been tricky so I would wait the extra day.
 
There's no real hurry to raise the CYA. I'd leave it at SLAM level for another day or two, then let the chlorine drop to normal level for 30 CYA, manage at that level for a few days, and once you're SURE your FC consumption is normal, then start to raise CYA. You'll be much happier with yourself if you find out in a few days that you didn't catch all the algae and have to SLAM again if your CYA is at a lower level.
 
Did u ever check/scrub all your nooks & crannies? Light niche, water features, ladder rails etc? Best to be completely sure before proceeding.
 
I dont really have light niches but with the small pentair LED lights I have butbI scrubbed them anyway. I brushed all sides, corners, ledge lounger chairs (top and bottom), inside skimmers and behind weirs. I didnt do inside my water features, but all I have are sheer decents...dont think that can be done. No ladders.
