I’m not criticizing you friend, I just think you missed the point of their comment. Potato head clarified pretty articulately, so I’ll just defer to their response.
Sorry I dont get it - I wasn't talking about BRS's video - I was responding to a specific question:
I don't know if Randy Holmes-Farley is reading this thread, but I do recall him mentioning before that it takes more alkalinity dosing to maintain higher dkh levels in the tank. I'm not smart enough to know why! lol
This was my reply:
because Alkalinity is what dKh is a measurement of .... In other words - to increase the dKH - you have to dose more alkalinity.
Dont know how to go further from here on this specific subject
