PH 8.4

[radreef02]

So I started a co2 scrubber. It was raising pH to 8.2-8.34 well I turned on my kalk to start raising alk and 8.45 happened just now.

The days with 7.9-8.0 was kalk only

Do I need to stop the skimmer ? Or turn off kalk and go 2 part. I have either or

My PH goes up to 8.5 with no ill effects. Growth and Alk consumption goes way up too

I think you will want to wait until you exhaust your CO2 media before you make any decisions. I think if CO2 media replacement cost wasn't a factor, everyone would just use CO2 scrubbers all the time.
