Anything bad about high ph?

[Canadian Man]

Nothing really diffrent. I just let them sit at room temp instead of in the tank but that should have made no diffrence as you adjust the temp dial when calibrating anyway.

I think the monitor may have shifted cause it was giving the same reading at first on but then the next day it was out. I had it sitting in my effluent cup instead of the tank water but I cant see how that made any diffrence.

So anyway at midnight on Thursday the ph is comming in at 7.98 so 8.0.
