CC at 1 following SLAM?

[PoolBrews]

Hello!

I just did my first SLAM on my new pool... followed the directions pretty well (I think). Once I passed the overnight test, it took 3 days for my FC to drop to below 10 - I was running at 28 for my CYA of 70. Pool is crystal clean, but my FC is at 9, and my CC is at 1. Shouldn't it be 0? Do I need SLAM again?

Complete readings today:

FC: 9.0
CC: 1.0
pH: 8.0 (already added muriatic to handle this)
TA: 110
CA: 400
CYA: 50

Thanks in advance!

Give it a day and it will probably go away.

I've heard that CC's out gas after a SLAM. Does the use of a solar cover affect or slow down this process?

Solar covers slow down the removal of CC.

Did the SLAM end up being a success? I’m at 70 cya and started a slam, some people say to partial drain.
Thanks

Yes, the 1 ppm CC went to .5 in the evening and was 0 the next day - all is good!
