My BioCube 14 has been running since 2011. I had 3 Korellia Nanos (2x225, 1x425) that ran 24/7 from day one. Well, the other day when I was cleaning them, I was shocked by one. So they left. I still felt a slight shock. So I decided it was time to replace them. Before this arrived I did a stray voltage test. 3.8V! With this new pump. 0.8V! Big difference for me AND my fish as they have to live in it. I turn the regulator down to its lowest setting and it's still more powerful than the three pumps I had previously. He collects all the rubble that others missed. I would recommend this for a 20 gallon tank as a minimum size if not keeping SPS. This should be perfect for when I start adding sticks to my BioCube.
