Ca vs Alk availabilty

[Kjames]

I am clearly a visual learner and it brings me great joy to see in real time the decreasing availability of Calcium with rising Alkalinity, courtesy of my new Trident. I've read it a hundred times, but seeing start to drop after the addition of Sodium bicarbonate in my own system in a visual representation is super cool. Just had to share.

I'm not sure I agree with the interpretation of these graphs as "decreasing availability of Calcium with rising Alkalinity ", but can you clarify what you are dosing when?
