I opened my pool recently and followed the SLAM process carefully, with great results. But now that it’s done, I’ve been sitting on high chlorine levels (26 ppm) that are not dropping. My target level for SLAM was 24 based on 60 CYA (it’s a salt water pool) so this seems about right. Since it hasn’t been sunny, I’ve been keeping the autocover on it. So the question…do I wait for a sunny day, then leave it uncovered, or is there another way get the chlorine back down to the 6-10 level?

Why the rush to get your FC lower?
Is your SWG off?
Leave your cover open during daylight.

SWG is still off, of course. I’m just interested to verify my pH is good. It was 7.8 before I started the SLAM. It’s a great guide and well written.
So also, one of the last things I did at the end was to add some DE to my sand filter to help clear up the stubborn cloudiness. This was effective, but I had to repeat it 4 times because not long after adding it, my pressure would climb and my pump would struggle to maintain prime, resulting in needing to backwash to clear it. So the DE is very effective, but just wondering if that seems reasonable.

pH is fine. Leave it alone. The pH test is not valid when FC >10.
What is "that?"
I think he was referring to the rapid climb of pressure after adding DE? Sounds like the DE was doing what its supposed to do.
