Odd works around

I do not really get it. (what you mean). Do you mean that I´m wrong with the relationship between aeration (skimmer), CO2 content water/air and pH? Or is it only uninteresting for you?

Not at all, do not have GHL, Trident. Just had read UR original post and was curios, thank you.

Can't you control a pump's flow (via 1-10v) based on a flow sensor's output? (ie. control pump up or down)?

Yes I can control it with help of an illumination curve - no problem - I can adapt that to my pH curve.
