I really liked this fountain, small yet nicely designed. The only negative was that the water sound was not loud enough and the pump is quite annoying to keep on the bottom of the bowl. A trick I found that makes the water sound a bit more "bubbly" was to place one of the smaller rocks right where the water comes out from on the second highest tube. Dont block up the flow though, choose a thin rock that still allows water to pass out. The rock being there causes more pressure and creates a deeper sound.
