It's because he remembers putting 3 spoons of bicarbonate in his tank 20 years ago! And it should of given him 2dkh but instead it gave him 1 dkh! Weren't you listening?From 6:30 - 8:20 David asks Claude specifically about the potential spike in alkalinity. Claude responds with, and I'm paraphrasing, that seawater chemists now understand what happens and although it may appear you are dosing 2 dKH, it's actually 1 dKH because it comes back throughout the day because of seawater combining rock surface and organics in the aquarium. I did not hear reference to alkalinity spike anywhere else in the video. Interesting though, Claude acknowledges the "many posts on Reef2Reef" ;)
Yes. I heard him trying to turn this thread around in his favor. Bold.
Also, seawater chemistry is different than standard chemistry. And bicarbonate in Europe raises the pH but not in the US. Got it?
