Air pumps do cause CO2 depletion and potentially pH swings. In my 
particular case, I have a high KH, so pH swings are minimal. (I don't 
switch off filters either, as I like to have a biofilter just in case.)

BTW, I don't use a "normal" air pump for my size of tank... I use the 
smallest one I can get. So it's really just a minor turbulence.
