Thank you for the video. It makes sense now why I have lower pH.

I have a CO2 scrubber as well as have that line outside the house. I dose Kalk in my tipoff water and still my pH at night/ early morning is 7.2 and high of 8.02. I give up.
I am tempted to push my Alk to 10 or even 12 just to see how the pH would react. But I don't want to tempts fate. I have had many issues with this tank, so why rock the boat. Plus the Alk swing won't be good for the corals. But it'd be interesting to see the result.
There are two effects from raising alk. One is the effect of the alk itself, and the other is from the additives used.
The rise from 8 dKH to 10 dKH (ignoring the additives used) will effectively boost the pH from, say, 8.0 to 8.1.
I have that exact ph pen. It tends to drift. You can purchase solutions to check it with. Try horticulture.
Thank you Randy for the actual number. My fear is, with the alk swing how the corals are going to react.
@Randy Holmes-Farley , is there a chart to look up alk to pH values (assuming calcium is stable at ~420)?
Also, what is more important? The upper range or lower range w/the pH day to night swings?
