no they don't really effect O2 or CO2, though disturbing the surface will help add O2 and disperse CO2. a spray bar is better. they can look good though. some fish like to play in the air stream.are they actually worth getting? airstaones that is? i am sure i read somewhere that they dont help the oxygen and co2 levels? really
??
cheers

they do help with oxygen...
They cause water movement in the water and create surface disturbance allowing greater gas exchange. Why do you think they are recommended when medicating?
