What is everyone’s thoughts on my PH. I know it has a lot to do with incoming air, aeration, etc. I’m not so concerned with that stuff.

By looking at my graph, you can see I have a minimal daily swing, which is good, but, the question is, is it riding a little to much on the low side?

System - 250’ish total gallons
Alk- 7.7 - salifert
Cal- 435 - salifert
Mag- 1290 - salifert
NO3- 5 - salifert
PO4- .07 - Hanna
Salinity- 1.026 - refractometer(calibrated)
Temp- 76.6 - Apex
PH- 7.97 - Apex(current as of now*lights off*)

Just looking for opinions, thanks!

Doesn’t seem bad, more aeration will reduce/eliminate ph swings.
