A couple questions, a couple blips cc and aereation

[Msch99]

Hey all,

See logs below. I had a couple blips where the cc went to 1.5 and 2, is this normal? They were on the 29th and 27th. Also now that I have the TA close, should I block the aeration nozzle now that I do not need to actively raise the PH?
Thanks! *Note: The times may not be exact, I entered the data into the app yesterday things went a little funky, keep the right date but saved as the time I entered even though I entered the time and used the check mark. Went back and changed times from the overview and seemed to be ok.
Mike

If you no longer need aeration, certainly stop aerating.

The occasional spike in CC despite otherwise good readings makes me suspect that maybe someone peed in the pool. Or you had a bunch of dirty, sweaty bodies in recently.
