I could get LOTS of oxygen in my water if I moved my Fluval spray bar above 
the waterline. I use a 303 on a 30 gallon tank, which is far more than most 
planted tank people use. The point is, though, that an airstone can be put 
on a timer to operate at night only. During the day the surface agitation 
is kept to a minimum to prevent CO2 loss.

Filters don't add oxygen to the water unless they agitate the surface. 
(wet/dry filters and biowheels being the exception.)
