I own and use a pair of Marineland Penguin 1140's. I have had these for the last ten years. They are currently being used on a 110 gallon tank and are still running at the same 300 gpm as when I first purchased them. The ease of use and maintenance is very simple and easy.
They have on the 1140's, an attachable airline with an adjustable oxygenator regulator cap, allowing you to adjust the amount of air with a thumb screw. As far as the other sizes of Marineland Penguin Powerheads, I can not speak of their performance, but if they perform as well as my 1140's, I believe there should be no further discussion.
