I stopped using the power head because I wanted to try the air driven filter. I don't like depending on mechanical motors and such if I don't have to. As I say this, I realize that the air pump is a mechanical devise, so I guess I'm not making much sense! Most of all, I like giving the fish a fresh boost of air in the morning after a long night of oxygen depletion. I don't run it very long. Most of the day there is no air and no circulation. I do have a pretty good bunch of guppy grass that pearls a lot during the day.
