Which one is your favorite?
Has to be blues clues with that orange red blue purple combo.

Next time you are filiming, can you get a quick video of your surface agitation. I feel like mine is a lot, but I can't get my PH to even 8.20. I'm even freezing right now with the window open since my tank is in my office. I also run a CO2 scrubber. But I do have a canopy....the canopy is 90% open on top, but the big T5 panel may act like a lid.
Theres limits too. He must have ridiculous consumption during peak. If your indoor air is 409ishppm, theres only so much you can do. More air exchange wont necessarily change pH if youre already maxed out.

The biological processes in the tank also change the pH value. When coral is consuming its reducing carbonic acid in the tank and increasing pH. for instance, i can dose the same amount of kalk on the hour, same flow, and same indoor CO2 and still see that .3 swing, largely attributed to happy/growing coral. The only thing i could do is dose kalk in the middle of the night to try and stabilize it but my peak would still be lower.

His .5 pH swings are literally indications of peak happiness in a tank. Thats wild.

I'm not so sure it's necessarily the boiling of a surface as much as lifting the lower water up to exchange with the air
Its just the mere fact you have a metric boatload of flow and your allowing the coral to be happy, which becomes a positive feedback loop of additional consumption.

At least thats my interpretation. More flow = more growth = higher pH. The air exchange contributes but if you shocked your coral from a swing you'd see your 8.5 turn into 8.2 with all other variables the same.

Looking back this is about the best I can get. Definitely less than a .5 swing for me.

If I open windows it gets a bit higher but probably nor necessary. If a bunch of people are over it's lower
