I know not everyone has this issue but my PH bounces between 8.4 to 8.65 daily. Is this too high? what would be a better range. I have outside air to my skimmer and could shut it off completely or only turn it on at night. I run kalk which after running outside air is giving me this high ph. Corals look good. It's an easy thing to adjust for me. That's why I am asking.
