Ok, I purchased a jebao wp10 from [USER=3722]@Eric Noa[/USER] and am very impressed. The pump is tiny, hardly notice it but it puts out the waves even in my 72g. I am running an mp40, not even in the same class because of size, but it was worth the couple of dollars over the 485 dollar mp40. The reason this is great for my application is i shoved one side of my tank to the corner of the wall and I don't have the room and moving a tank is just out. It is so quiet and give it 2 thumbs up. I really laughed when I opened the package and thought what is this little guy going to do, and it does preform. I really like that it isn't programmed in and it is a step up from a 1050 hydor.
