how about some small foreground plant?
The filter in my EBI doesn't make any noise at all, the spray bar is about 1" below the surface. Are you sure there isn't some air or something trapped in yours? Or are you keeping the spray above the water?I like the filter because of its compact size, but it does get a bit noisy. I'm gonna have to put more holes in mine. I wish they made a spray bar about 3 inches longer, because that would help as well. I might grab some black gravel to cap it with. Just a small layer to hold it down some. Im going to the LFS later today for some stuff anyhow.
+1 on that, mine doesn't make even the smallest amount of noise and I have it 3 inches below the water line. I turned the filter down to about 50% , that thing is powerful for this small of a tank.The filter in my EBI doesn't make any noise at all, the spray bar is about 1" below the surface.
