in my new tank i havent set the sump up yet, as i havent enuff water, but i was wondering, as there is no skimmer, are my fish gettin any air in the water? i am using some koralias to move the water and the surface is being broken, but just to make sure, i connected up an air pump. its not perminant, so its not to nasty on the eyes, but was i thinkin right??
