Is PH of 8.5 a concern?

[TheReefDiary]

My pH is currently sitting at 8.5. Normally during the day is 8.3-8.4. Today I've noticed it sitting at 8.5 is this an issue? Only things I dose is alk.

It's fine. I run that all the time, and higher.

My phosphates and nitrates crashed for a couple days and brought about dinoflagellates. Tank parameters are solid, but missed the tanking nutrients.

So happy to know this level isn't another issue.
