Just started SWG and getting unusual results from testing

[AZRider]

Hello,

I started up my IC40 last Saturday on our new pool build. I had FC at 6.0 with CYA of 60 before startup Did OCLT test friday night no drop in FC and no CC. Salt cell is generating chlorine and seeing bubbles at pool returns. I ran OCLT last 2 days.
1st day
Morning FC 5.0 CC 0
Evening FC 6.5 CC 0
2nd Day
Morning FC 5.0 CC 0 1.5 lost FC overnight no CC
Evening 6.0 CC 0
Today
Morning FC 5.0 CC 0 Lost 1.0 FC overnight

I read that my FC should drop during the day due to sunlight, not raise and overnight FC should increase not decline when you have 0 CC.
Using liquid chlorine before adding the SWG would consistently drop 1.0 FC during the day. Is the SWG change output based on time of day?
Pump is running 1850rpm 21 hrs/day 47GPM
Any ideas?

1 ppm is within the margin of testing accuracy.

You look good. I would not change anything except to up your FC a bit and run it 7-8.

Thanks, I will adjust the output up and keep doing what I am doing.
