Try dosing alk an hour before the low point and soften the trough in the pH drop.Last few days I see now 8.3 in the day and 7.5 in the night.
Anyone any numbers to share???
Strange question.
If surface agitation is the primary transferance area during emergency procedures with power loss and a battery backup air stone,
is a weighted open airline with heavy splashing better then a lime wood air bubbler with a column of tiny fine bubbles?
Is the difference small enough to not really matter?
Thanks!

Randy, sorry for not being precise. I see on Cruz response it misleads to PH.That's pH or O2?
If pH, it's a big drop. if O2, it's pretty high.
Agree Randy.That's quite a high DO level for a marine system, but I have no idea what levels are optimal.
Agree Randy.
That’s why I’m looking for some numbers to be shared.
I do have previous numbers of 7.7mg/L which I had minor issues with corals on my tank with all other chemistry parameter in good range as per ICPs.
Another tank with huge issues of all sorts and extremely haze looking water had 7.6-7.7
Hence I like others to join and share some values where possible.
Not considering the pressure losses from the flow meter. So this measure is unlikely very accurate but good for reference to compare after the skimmer mod.
Very good thoughts and ideas ;-)Just a thought . You went from a poorly running skimmer to a better on. One would think that you are removing more dissolved organic's using a smaller bubble in the skimmer. This would cause the increase in DO. What is the DO in a batch of fresh salt for a reference. Also are you running a redox probe , I would like to see the difference in the number compared to the DO numbers . Polyp extension and looking better might be due to the tank running cleaner .
Very good thoughts and ideas ;-)
What if I run the skimmer with open skimmer valve and return the skimmate back into the tank, would I still see the increased DO in that case????
I run a ORP probe, but unfortunately it's not good anymore and out of range. Did not see significant changes when running higher DO. This not very trustful probe showed about 50-80 higher readings with compared to the old skimmer.
ORP is really complex as we know.If the orp is increasing even if prob is off , I would think that the water is cleaner with the new skimmer increasing orp.
I might need to get a meter and see. I know if I run the bubbles in my skimmer smaller orp increases / if I run large bubbles orp decreases.
I run all gf-signet probes that are calibrated way different than hobby grade probes.
