You see this was edited and you still went for it anyway, ill elaborate a measurement someone in this position measured is probably not accurate. checking ph ranging from 8.06-8.02 is pretty difficult, then to worry about that kind of swing is just not necessary so that's why I say don't worry about ph that critically, unless your testing that way too.That statement has little value in a thread like this.

Given a choice between a ph level that stays super stable at 8.02-8.06 during the day or, one that ranges from 8.1-8.4 during the day, which option would be the most beneficial for corals. I realize staility is key. But how key is it compared to achieving better ph levels but much more volatile?
Regardless of the small range of the ph swing and the accuracy of the test, the point was a stable ph vs a higher ph that moves around. At no point was I asking you if I should “stop the ph hype” I can make my own decisions on what I want to do. Was looking for some opinions by people who know more than me.You see this was edited and you still went for it anyway, ill elaborate a measurement someone in this position measured is probably not accurate. checking ph ranging from 8.06-8.02 is pretty difficult, then to worry about that kind of swing is just not necessary so that's why I say don't worry about ph that critically, unless your testing that way too.
I have two ph probes calibrated by me the same way, running off my hydros and they differ more than that range, now how can you be critical to .04 swing if your testing is questionable.
Thank you for the responseI don’t think there is an clear answer to that, Nor even a simple definition of what beneficial means, but I think many hard corals will grow faster at the higher pH if there are sufficient other nutrients available.
Also, again, it was edited well before he quoted it. So everything after is un debatableRegardless of the small range of the ph swing and the accuracy of the test, the point was a stable ph vs a higher ph that moves around.

You've got multiple variables here. You can't make that assumption.So just to get back on point here, I was dosing kalk and ph was ranging between 8.1-8.4. The sea fans were acting upset. So I wanted to try stability and ph has been super stable between 8.02-8.06 and they are back to normal. So, I’m wondering if higher ph is only good if you can also keep it stable.

Bio-availability of certain elements at a given pH range would be important, right? In addition to how proteins fold in a certain pH would be important. What about the ability for the cell membrane on the outer most epithelium of the coral doesn’t have to expend energy to maintain its cell’s pH. I am sure there are plenty of papers beyond just corals that demonstrate that.
but the whole debate could be just splitting hairs at this point. As long as your system is working well and not to an extreme. Whether it be a calcium reactor, 2 part, 1 part, or kalkwasser, as long as it’s stable and not extreme. Like 7.7 ph or 8.7 pH. Landing in the some where in the middle is fine.
Alk was 10.2-10.6 with ph at 8.1-8.4 when I was dozing kalk. After going back to no dosing of kalk and daily water changes, ph stable as can be at 8.04 and also stable alk at 9.2.Did the alkalinity change between those scenarios?

My first question is would dosing throughout the entire day be better for my PH stability ?
Second should I look supplementing some Kalkwasser to keep my PH closer to 8.3?
Finally should I just wait until I get my alk to stabilize and hope this leads to a more stable PH?
Thanks for this great info Randy! I currently use BRS Two Part, are some other brands better for PH ?Depends on what you are dosing. The conundrum is that high pH alk supplement dosing at night stabilizes pH best, and alk dosing during the day stabilizes alk best.
I don't know that you "should" do it, but hydroxide dosing (limewater/kalkwasser or ultra high pH two part) is a good way to help raise pH.
Stabilizing alk is not typically a solution to unstable pH. pH is determined by CO2 and alk, and the variation in alk is generally much less than the variation in CO2.

I know this is an old thread at this point but wondering if you still run your tank(s) like this and if so, what your current method is and the programming you use.People always tell me i'm crazy for running my tanks like this, and admittedly, i only run some of them this way, but, i've had more growth with this method than almost anything else. They say don't chase ph?? naw, chase ph, with kalk...why not. PH shutoff which doses kalk or RODI depending. The only real black magic is figuring out what the PH shutoff needs to be to get to a target alk/cal range, but, with appropriate timeouts on my doser, i've made this quite safe.
Oddly enough, i'm wondering if your table might have answered the "black magic" bit some more
and here's the tank in question.
