Now that I got the answer for my last question about needing an air pump or not I have another question.
http://answers.yahoo.com/question/index?qid=20070911192131AAfI11y
I have the external type filter on my 55 gallon tank that has two charcoal filters in it. This type filter spills water back into the tank creating air bubbles on the surface.
I also have an air pump. Is it possible to have too many air bubbles in the water? Will it harm the fish?
