I was looking over my numbers and noticed something worth mentioning. I usually have a daily pH swing of 8.05 to 8.28 or so. This is with the skimmer pulling air through a CO2 scrubber. The day after I mounted these frags we went on a 3 day trip. When we came home, the pH read 8.68/Alk 7.6. Alk is usually 8. It's hard to believe the pH could be that high, but in a house with no one adding CO2 and a scrubber... maybe?
Does it seems likely that the combination of
A) frags being stressed from handling, mounting and
B) this pH spike, could be the cause of the onset of STN?
