PH change cause issues?

[m.kristoff]

Hello
I recently setup a co2 scrubber on my skimmer and have I set it up to recirculate. My PH went from 7.8-9 at night and about 8.02 for daytime highs. Its now 8.1 at night and 8.2 during the day. I have a few SPS frags and I am hardly getting polyp extension since the change.
Calcium is 410 and Dkh is between 9.18 and 9.4

My thinking is to be patience, but I wonder if PH rise would cause this?

My duncans, frogs and torches look great. same with my bubble and anemone

Any change that is fast will cause a reaction if SPS. You always want to keep a constant PH as Themis will effect your dKH

I figured as much. I was surprised how much my PH changed. I had the co2 scrubber getting outside air. as soon as I changed it to recirculate, it jumped up that fast

Any thing happening fast is always a bad thing.

agreed. no way to ease that change in- In the long term it will be better
