Not really. A good skimmer will keep your tank water quality/conditions pristine. Its not a matter of how much air, how tall, how wide. If your water quality is good enuff then the skimmer is good enuff. Simple.
Also another good way to judge a skimmer's abilities is by feeding more. If you can feed a lot of nasty nutritional stuff to your tank but the water quality does not waver, dats an excellent skimmer.
Its also about balance, having 2000L/hr of air and 6000L/hr of water injected into a 6 inch body aint gonna do too much good cos of the turbulence created etc etc. Just an example.
