On the topic of Alk monitor, a couple of guys in Asia developed a piece of equipment that claims to do it:

The technique doesn't look like rocket science and I hope a more affordable and smaller versions come to market, soon.
Ill buy one! Alk is imo the most important and annoying parameter to monitor. Any updates?
That was my thinking, Randy. And I suspect that my tank is probably typical in that regard. However, reading through the article I linked above, "Results of this investigation demonstrate the difficulty that corals encounter in shedding waste protons generated during calcification. High rates of H+flux continued for several hours following peak Gnet" and, "...corals can cope more effectively with the problem of DIC supply compared to the problem of eliminating H+." The conclusion of the authors in this study is that pH is a bigger issue for the corals than alkalinity. Food for thought.
Sorry to resurrect an old thread, but is eliminating H+ harder at lower pH? I would guess so, since the concentration is higher, but I’m no chemist
Thanks for the explanation @Randy Holmes-Farley.
Do you or @JimWelsh know anything about the Protein Flux Hypothesis? I read about it in the paper that Jim referenced earlier, but I was only able to find a single reply to it in the literature. Perhaps it's pointless to chase, since it seems that alkalinity plays a much more important role in calcification rates than pH.
