The level of carbon dioxide in the tank will vary how much alkalinity you get from your kalkwasser mix I believe. When I run my skimmer air line outside, my tank ph goes to 8.2 from 7.8 if not running the air line outside. I need to use much less kalk when the ph is low, I'm guessing because the kalk reacts with the co2 more
