Is this a normal Ph trend?

[DVeit]

What the title says. This is my ph graph over the last few days. Is this normal? I've been battling low ph for a while now. I have my sump light (cfl in Home Depot fixture) on reverse cycle from my DT lights (2 kessil 360we's). My skimmer runs 24/7 (reef octopus 110). Kh at 9.5. And I get plenty of airflow over sump and my wp-25 breaks the surface with every wave.

Totally normal and acceptable.

I see nothing wrong with this. Looks SUPER normal.

here is mine the last 10 or so.

Ok. Well good to hear. Was just thinking it should be a little more stable than that. Thanks!

The pH is going to dip at night unless you have a refugium with a light on an opposite cycle to your main lights.
