In the fall and winter its more in the 8.2 range as I have a vent that's open for fresh air in the room.

very similar situation----is 7.8 the lowest it goes or is the kalk reactor set at this point. the reason I am asking because mine will drop over a week from 8.1 to 7.7---at that point I either use calcium hydroxide or buffers depending on the alkalinity level.
If I left it alone would it continue to fall or would introducing something so basic as opening the basement windows and or using an air stone help?
