No, it is not a UGF. Basically its a very powerful pump, I had an extra tube from my Fluval filter, I poked some holes in the tube and stuck it in the pumps intake. The pump is so powerful trying to suck the water in, the holes in the tube do not allow water to fill in the tube fast enough thus mass amounts of oxygen gets through.TankBuster said:Is that an ugf? Where does it draw the water and air from? I want one of those for my 250.
