You are more than likely have the same problem many are having. It has been

couple of
windows and direct a fan to blow out room air and pull in outside air. The
next day the pH
will probably be back were it was. You can also start a kalk drip, if needed,
as kalk
"eats" up/reacts with CO2.

Ca(OH)2 + H2O=== Ca++ + 2OH
