Step 2Assembly
I then experimented with water levels (if too much of the pump sticks out of the water it won't pump well), rock placement, and flow speed (this pump is adjustable).
To make sure the tubing stayed in the bent shape, I heated it carefully and bent it by hand. I was careful not to do it too much because I didn't want a radical bend, but it seemed to work. I tried a burner on the stove, but found that a lighter a few inches away for short periods worked better.
Then it was just a matter of placing the rocks so the flow of water looked nice and didn't make too much noise.
