Is my SLAM finished?

[Fire]

I'm trying to determine if my SLAM is done.

Water has been crystal clear for 3 days at 31ppm with 80 CYA.
Did the OCLT last night. Test at 10pm was 31ppm and this morning at 6am it was 29ppm.
Is it normal to lose 2ppm with such a high chlorine saturation (31) or do I need to keep SLAMming until I have a loss of 1 or less. It rained around 3mm overnight.
Thx

Tried to look at your test history during the SLAM but it is not entered.

If the water is crystal clear and no CC, let the FC drift down today and do a Overnight Chlorine Loss Test tonight at a FC around 20 ppm.

I won't be home till tomorrow morning at 7am. It's overcast and raining 3-5mm here today (Toronto). My SWCG is off and pump is running 24/7. Any thoughts as to what should I expect the FC loss to be tomorrow morning?

I was using the pool math app to determine chlorine needs during slam and logged it on a piece of paper. Next time I'll log it on the app.

If cloudy all day your FC loss will be less than if sunny. So less than 50%.

So I did the OCLT test last night. Went from 24.5ppm to 22ppm over 10 hours. I'm assuming I haven't passed the OCLT test? Or is my FC too high and need to bring it further down to get an accurate OCLT?
