I have an air pump for an air pump for a 60 gallon tank in my 15 gallon tank and have a volcanoe and two carbon filter attached to in for my under gravel filter. My question is how does this work? What is the carbon for? There does the stuff get filtered? Wouldn't the "stuff" just float back up? I was so confused that i added a hanging filter just to be save. How does this air system work?
