I want to put a small powerhead against the back wall of my tank to increase the flow behind the rockwork in my 20L. Does anyone have any recomendations for a small powerhead?
I have used the little Micro-Jets, two in the nano I had, and one in my top of reseviour that pumps top off water into my sump. They are really small, like maybe 2x2 inches, so it might be easier to get in and hide that some of the regular Maxi-jets.
