For me low PH means not enough oxygen in your water.
Aren’t there other factors that could cause pH below 7.8?
For example:
Your saltwater mix
Lack of sufficient gas exchange
Nitric acid build-up from biological filtration
Production of organic acids from metabolic waste products.

Lol. pH is not a measure of Oxygen.For me low PH means not enough oxygen in your water.
I don't believe the title statement is true.
Why? Happy to learn and modify or remove it.
From the link...
If your pH is less than 7.8, it can be from the following causes:
#3 & #4 are super unlikely as you would notice these issues. #4 would cause you health issues such as headaches, lethargy, etc... These are super easy to rule out and super uncommon.
- Inadequate tank aeration that leads to the accumulation of CO2
- pH-lowering dosing such as a calcium carbonate reactor
- Super-high stocking levels that would cause in-tank issues
- Unhealthy levels of CO2 in your tank location or house that would cause you noticeable health issues
So if your tank has good aeration, your house or tank area has normal indoor levels of CO2, your tank is not super overstocked, and you are not dosing anything that lowers pH, any reading below 7.8 is not accurate. Your meter is not giving a realistic number.

I just don't think people followed the link to know that this was a side trail from the original post.
Regardless, since the title is wrong, I do not think it appropriate to just follow the link and leave a flashing light of misinformation.
Why would it need to be a mismeasurement?
Tanks often have excess CO2 relative to the air at night.
Even if one assumed equilibrium at the nightly low, pH 7.7 at 7 dKH alk means about 1250 ppm CO2 in the air.
That's hardly unusual:

A friend just changed out his sump on his tank. His original had multiple baffles. His new one has only one. His PH is now 7.8 where in the past it was 8.3Lol. pH is not a measure of Oxygen.
